[M]M6220651[/M] has a 96.568bit (30digit) factor: [url=https://www.mersenne.ca/M6220651]117465933684061090230298707631[/url] (P1,B1=3000000,B2=243000000)
96 bits. at this exponent size, this is a beauty. 
Not the normal kind of factor posted here, but I was YAFU'ing a C107 that was already ECM'd appropriately, but YAFU 1.34 likes to recalculate ECM effort and do a few more curves, which actually worked beautifully this time:[code]current ECM pretesting depth: 35.52
scheduled 67 curves at B1=3000000 toward target pretesting depth of 35.67 prp37 = 5217870316310181049264840173981775799 (curve 1 stg2 B1=3000000 sigma=3040696252 thread=0)[/code]The first (second?) curve split the C107=p37+p70 What I expected to take ~8000 seconds took 9.5s :w00t:

Nothing spectacular, but the first P1 tests I did in a while and the first to finish stage 1 returned:

This was a "oneoff" timing test.
