My FIRST Fermat Factor, and the first discovered by an Italian
March 1st, 2021
New Fermat factor from Luigi Morelli! 74327396788321657 . 2^{42}+1 is a Factor of F_{40}!!! Miracles happen from time to time... and I discovered the second Fermat factor of this year, my very first on my birthday's week! I started searching with Leonid Durman in the late 1990. The factor has 30 digits, and was found using a Intel 9800x with a Nvidia RTX2060 and the program mmff from George Woltman. Congratulations to FermatSearch, we now have 357 Fermat factors known!
