When looking at this result, I was expecting it to be yet another composite factor. Turns out it wasn't:
M12731681 has a 151.792bit (46digit) factor: 4942614515973735792916302243662188576877302039 (P1,B1=400000,B2=428459850) That will be 17th place on the Mersenne top factors for P1 and is by far the biggest factor I ever found with P1!

Whaaa! Congrats! Nice found!
Same number of digits like my best (currently position 13), but it falls about 0.9 bits shorter Last fiddled with by LaurV on 20220506 at 02:30

Getting lucky again with my P1 factoring:
M12782851 has a 235.159bit (71digit) composite (P21+P24+P27) factor: 61645213700098762638579831947213762951673986053039553206940532463429217 (P1,B1=400000,B2=428459850) That's the biggest triple factor I ever found (out of 4 in total).

I finally found one that made the top 500 in this list https://www.mersenne.ca/userfactors/pm1/1/bits.
https://www.mersenne.ca/exponent/3884411 has a 123.607 bit exponent. currently at #384 and the first factor I have found larger than 109 bits!

But according to your personal factors list, you've found this and 4 other factors larger than 109.x bits, including two larger than this (131 & 136 bits, #84 & #158 in the top500 list).

Hi James. Are you the right person to ask about merging my two IDs as shown on that list (the old "Lord Julius" into newer "LordJulius")? If it's simple, I would appreciate it.
