That may help. I'll try it.

Maybe it's got a problem with the exponent P=103695649.

2004109083829816426995592902 = 2 * 3 * 281 * 29917 * 47269 * 8106041 * 103695649, so the biggest factor is 103695649, the exponent, which is bigger than B2=20264000.

Is it possible it's not accounting for the special form of Mersenne factors, which allows ignoring P as a factor of Q-1 (Q is the factor found) and only using the general rules for factors found by the P-1 method?

That's probably it.

You have bet my best. I am in the 120 bit club too. Very nice catch.

Your 98.x factor directs to 83.x factor and 101.x factor directs to 98.x factor.

 2021-06-13, 10:06 #1891 LaurV Romulan Interpreter     Jun 2011 Thailand 965310 Posts Fixed, thank you very much! (I didn't edit the quote in your post, only my post). I got lost in so many factors and links. But in this case, the 101 is not anymore "smooth". My mistake. As they were not yet on mersenne.ca at the time, I wrongly remembered their size (which is displayed when reporting), and I assumed the 101 was the smooth one (the "smoothness" is deduced from the amount of credit given, you don't need to do any calculation or to see the k value to know your factor is very smooth, hehe). Therefore, to repair the damage, take this new 115 bits guy here... Last fiddled with by LaurV on 2021-06-13 at 10:11

Um, I don't know how to check the result. I just report what the screen and results file shows me.
