Thanks to all the GIMPS members that contributed their resources towards achieving this milestone.
Join now to help GIMPS press onward with verification tests to prove M(43112609) is the 47th Mersenne prime.
To recognize all those that contributed to this discovery, official credit goes to Cooper, Woltman, Kurowski, Blosser, et al.
The new prime number is a member of a special class of extremely rare prime numbers known as Mersenne primes.
It bests the previous record prime, also discovered by GIMPS, by 910,807 digits. If every second you were to write five digits to an inch then 54 days later you'd have a number stretching over 73 miles (118 km) -- almost 3 miles (5 km) longer than the previous record prime.David Stanfill also verified using Cl Lucas on an AMD Fury GPU. Their first record prime was discovered in 2005, eclipsed by their second record in 2006. Cooper lost the record in 2008, but reclaimed it in 2013, and improved the record with this new prime.Finally, Serge Batalov ran Ernst Mayer's MLucas software on a 18-core server to verify the prime. Cooper is a professor at the University of Central Missouri. The primality proof took a month of computing on a PC with an Intel I7-4790 CPU. Cooper and the University of Central Missouri is the largest contributor of CPU time to the GIMPS project.To be thorough, the prime number was independently verified with four different programs running on various hardware configurations.In recognition of the individual discoverer, the software authors, the GIMPS project leaders, and every GIMPS participant's contribution, credit for the new prime goes to "Jonathan Pace, George Woltman, Scott Kurowski, Aaron Blosser, et al.".
