AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Oh man what the fuck i just joined GIMPS because I watched the veritasium video on it and I was like ooh I don’t use my computer for anything lemme contribute my little bit of RAM and I come to find out there was a 6 year gap between the last discovered one and the one discovered a few weeks ago???? 😭😭😭

[positivelyprime]

After a week of checking and some 6 years of waiting, we have finally found a new largest prime!!! This modest number is given by

p = 2^{136279841} - 1

and has more than 40 million digits! This was, of course, found by GIMPS.

C'è chi invia i buongiornissimo caffè, mentre io vi saluto dicendovi che è stato appena scoperto un nuovo numero primo, avente la bellezza di 41.024.320 cifre, ovvero

Queste sono le robe che vorrei che mia madre mi inviasse la mattina su Whatsapp.

What’s prime grid

So a hobby of number fans and mathematicians alike is looking for big prime numbers. Because if you find one, you’ll have a small dose of fame (and sometimes prize money). Of course, the prime numbers we know of are so large that you can’t feasibly check them all by hand anymore, so you have to get computers to run them.

There are two competing projects to find big prime numbers: GIMPS and PrimeGrid. GIMPS (Great Internet Mersenne Prime Search) is dedicated to finding bigger and bigger Mersenne Primes (2^n -1), because Mersenne primes are really easy to check—their sieve is really simple for binary computers.

PrimeGrid runs a bunch of other sieves looking for different kinds of prime numbers, like 321 primes (3*2^n ±1), Proth Primes (k*2^n +1), Cullen/Woodall Primes (n*2^n ±1), Generalized Fermat Primes (b^2^n +1), and more. These aren’t necessarily going to be the biggest, but they are mathematically interesting for other reasons. For example, there’s an attempt to solve the Sierpiński problem (is 78557 the smallest k for which no Proth Primes exist?), called “Seventeen or Bust” (because there were 17 candidates when they started), which had found the 7th largest prime number (since dropped down to 11th place) by eliminating one of those candidates (there are now only 5 candidates). Of course, you can try to find the biggest prime number with their “Do you feel lucky?” project (“a real long shot. It borders on stupidity”).

Both of these you can run in the background on your computer, donating your excess computing power to advancing mathematics. GIMPS is its own standalone program. PrimeGrid runs thru BOINC (Berkeley Open Infrastructure for Network Computing), which you may know from Einstein@Home, Rosetta@home, or World Community Grid.

M136279841, as is its friends call it, is over 40 million digits long in base 10, and over 16 million digits longer than the last contender! It's also a Mersenne prime, which is the shorthand for a prime of the form 2^n-1; these are significantly easier to check for primality than other numbers, so they're usually the source of new world record primes.

This also marks the end of a 6-year drought in finding biggest-known-primes. That's the longest drought since the 1970s, and the longest in the history of the Great Internet Mersenne Prime Search (GIMPS), a volunteer crowd-computing search that's collectively set every prime-finding record for nearly 30 years. (Anyone with a decent PC can set up GIMPS on their own computer and go for the gold: the record set in 2017, for instance, was by a FedEx employee who ran the Prime95 software on their computer in their spare time!)

It's official: 2^136279841-1 is a prime number, marking the biggest known prime yet!

[somethingusefulfromflorida]

What is the largest consecutive prime number?  I mean, what is the largest prime for which we know whether all the numbers less than it are prime or not?  The largest known primes is 2^82589933 -1, which is 24,862,048 digits long.  The second largest known prime is 2^77232917 -1, which is 23,249,425 million digits long.  That means they’re 1,612,623 orders of magnitude apart, which is an unfathomably large gap; a million billion trillion quadrillions is only 46 orders of magnitude.  The number of particles in the observable universe is only around 80 orders of magnitude.  There are countless primes between these two that we just haven’t discovered yet, so what’s the highest number that we’ve discovered all the primes up to?

hey nyall should go help out with the Great Internet Mersenne Prime Search and do something semi important and brag to your friends that you helped do a math thing once

its freeeeeeeeeee

[erde-und-wasser]

today i learned that the biggest known prime number has 22,338,618 digits and is 274,207,281–1

isn’t that wild???

Vero: il più grande numero primo conosciuto è, a marzo 2022, 2 elevato a 82 589 933 − 1, un numero che, se scritto in base 10, è composto da 24 862 048 cifre. Tale numero è stato scoperto il 7 dicembre 2018 da Patrick Laroche nell'ambito del progetto Great Internet Mersenne Prime Search (GIMPS). Per scriverlo su un quaderno a quadretti normale, occorrerebbero 118 km di carta.

Vero: il recente sequenziamento del genoma, a cui hanno partecipato le Università di Padova e Udine, ha dimostrato che è ben 15 volte più grande di quello umano, il krill antartico - o Euphausia superba - è l’organismo animale più abbondante sul pianeta, con una biomassa totale compresa tra i 300 e i 500 milioni di tonnellate.

Vero:

Sebbene non abbia mai perso la sua funzione religiosa, parte della Chiesa del Santissimo Salvatore di Palermo, è adibita a meraviglioso auditorium, dovuti ai lavori di recupero dopo i devastanti bombardamenti del 1943 che in parte distrussero l'edificio, che si affaccia su Corso Vittorio Emanuele, l'antico Cassaro.

FALSO: l'uomo ha rubato una mattonella, scoperto dalle telecamere di videosorveglianza, nell'ala napoleonica della Reggia

Vero: "Se due persone dello stesso sesso chiedono il riconoscimento, e cioè l'iscrizione all'anagrafe, di un bambino che spacciano per proprio figlio significa che questa maternità surrogata l'hanno fatta fuori dai confini nazionali".

Così Fabio Rampelli, vicepresidente della Camera e esponente di FdI, nel corso della trasmissione In Onda su La7 il 19 Marzo 2023.

This past week, a FedEx employee from Germantown, Tenn., made a massive discovery — and it wasn't in any packages. John Pace found the largest prime number known to humankind.

And that number goes on to more than 23 million digits.

"So it's longer than anybody really wants to sit down and hear," he says.

If you're not great at math, here's a primer: Prime numbers can only be divided by 1 and themselves.

Pace found his prime as part of an online collective called the Great Internet Mersenne Prime Search, or GIMPS. Pace and thousands of volunteers ran software on their personal computers crunching numbers day-in and day-out.

Anyone can participate, you just need a computer, an internet connection and a lot of patience. Pace began his prime hunt 14 years ago.
