Grrrr... please stop posting trivial factors of ridiculously huge mersenne numbers. It was fun for the first few, and took us by surprise, but they don't have any value.
If you are serious, beat this. M(2618163402417 · 2^{1290000}1) has a factor 2618163402417 · 2^{1290001}1 (1290043 bits) (the largest "trivial" known, since 2016) Last fiddled with by LaurV on 20201208 at 05:08

60 digit factor, and what's left is a probable prime! Santa came rather early this year ;) Last fiddled with by nordi on 20201217 at 01:21
