[QUOTE=lisanderke;602076]I've found three 100+ bits factors yesterday! (the first one is the biggest one I've found so far :smile:) Out of a total of 6 factors found yesterday in this range, and 4 so far today.

This is from GMPECM, and an error on my part:
[CODE]********** Factor found in step 2: 223 20220404 09:43:03.243 Found prime factor of 3 digits: 223 20220404 09:43:03.243 Composite cofactor (2^73631)/223 has 2215 digits[/CODE] This is for M7363 which does not appear in any database I can find. I had intended M4363. Make of it what you will. 
[QUOTE=storm5510;603269]This is for M7363 which does not appear in any database I can find.[/QUOTE]7363 is not prime, therefore it's not a Mersenne number.
