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) What I expected to take ~8000 seconds took 9.5s Last fiddled with by James Heinrich on 2021-10-08 at 23:08 |

Nothing spectacular, but the first P-1 tests I did in a while and the first to finish stage 1 returned:
Code:
[Worker #3 Oct 24 07:53] P-1 found a factor in stage #1, B1=779000. [Worker #3 Oct 24 07:53] M107043329 has a factor: 9773787110913045103371451921 (P-1, B1=779000) k = 45653415314246463240 = 2^3 × 3^3 × 5 × 11 × 21841 × 317797 × 553649 |
