On 22 January 2020, 15:00:58 UTC, PrimeGrid's Fermat Divisor Search found the Mega Prime:

13*2^5523860+1 Divides F(5523858)

The prime is 1,662,849 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 115th overall. This is a world record for prime Fermat divisors, and it is also ranked 4th for “weighted” prime Fermat divisors.

The discovery was made by Scott Brown (Scott Brown) of the United States using an Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz with 16GB RAM, running Microsoft Windows 10 Core x64 Edition. This computer took about 39 minutes to complete the primality test using multithreaded LLR. Scott is a member of the Aggie The Pew team.

The prime was verified on 22 January 2020, 15:11:39 UTC by Stefan Larsson (288larsson) of Sweden using an Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz with 8GB RAM, running Microsoft Windows 10 Core x64 Edition. This computer took about 46 minutes to complete the primality test using multithreaded LLR. Stefan is a member of the Sicituradastra. team.

Glad to see that the subproject turned out one divisor. Hopefully we get another before it is all done.

Thanks everyone! I am really excited about the find, not just for myself, but for PrimeGrid as well.

Depending on how people decide to allocate there resources, I think DIV could yield a prime or two during TDP (maybe even another divisor) and be a factor in a couple of the jerseys this year!
