On 19 Apr 2012, 21:12:27 UTC, PrimeGridā€™s Generalized Fermat Prime Search, through PRPNet, found the mega prime: 773620^262144+1

The prime is 1,543,643 digits long and enters Chris Caldwell's ā€œThe Largest Known Primes Databaseā€ ranked 2nd for Generalized Fermat primes and 22nd overall.

The discovery was made by Senji Yamashita of Japan using an NVIDIA GeForce GTX 580 in an Intel Core i7-970 @ 3.20GHz system with 6GB RAM, running Windows 7 Professional x64. This GPU took about 47 minutes to probable prime (PRP) test with GenefCUDA. Senji is a member of the PrimeSearchTeam.

For more details, please see the official announcement.
