In mathematics, a Mersenne prime is a prime number that is one less than a power of two. That is, it is a prime number of the form Mn = 2^n − 1 for some integer n.
Using a computer powered by an off-the-shelf Intel Core i5-6600 processor, a FedEx employee from Tennessee has discovered the largest prime number known to humanity. At 23,249,425 digits long, it’s nearly a million digits longer than the previous record holder.
...
The new record-holding prime number, dubbed “M77232917,” was discovered by Jonathan Pace, a 51-year-old electrical engineer living in Germantown, Tennessee, on December 26, 2017. It was discovered as part of the Great Internet Mersenne Prime Search (GIMPS), a group that does exactly what its name implies. Mersenne primes—named after the 17th century French monk Marin Mersenne—are a rare class of primes that are one less than a power of two, expressed as Mn=2^n-1. In this case, the new prime was calculated by multiplying the number two 77,232,917 times and then subtracting one (277,232,917-1). The new prime is the 50th known Mersenne prime.
The FedEx guy gets the credit and the money! Something like US$ 3,000.

super cool for sure but come on.
this dude didnt discover #
Ramanujan ftw!!!
Indeed, the discovery of new primes is no small task; every candidate prime must go through the time-consuming and rigorous process of being cut-up by any potential divisors. Once a candidate prime is discovered, it has to be verified by outside sources. In this case, the prime was independently verified by four different programs running on different hardware configurations:
Aaron Blosser verified it using Prime95 on an Intel Xeon server in 37 hours.
David Stanfill verified it using gpuOwL on an AMD RX Vega 64 GPU in 34 hours
Andreas Höglund verified the prime using CUDALucas running on NVidia Titan Black GPU in 73 hours
Ernst Mayer also verified it using his own program Mlucas on 32-core Xeon server in 82 hours. Andreas Höglund also confirmed using Mlucas running on an Amazon AWS instance in 65 hours.
The Holy Grail of primes is yet to be found: a prime number containing 100 million digits. The first person to find this elusive number will be awarded $150,000 by the Electronic Frontier Foundation.
