[QUOTE=kruoli;551266]That's because Ryan found it, I only appear in another result line (if you were thinking about me). :razz:[/QUOTE]:doh!::doh!:

Yes, it was Ryan.

My biggest factor yet.
 
[M]M10464319[/M] has a 100.251 bit factor: [url=https://www.mersenne.ca/M10464319]1508190451550803761680015597777[/url]

I had this assigned for PRP-CF. When I found the factor, I quickly assigned it back, because for some reason, when a new factor is found, AID changes on server, resulting in unassignment in Prime95. When I tried further, I found nothing. But apparently I was too slow with re-assigning because another user got it assigned before me. :cry:

If I hadn't done another P-1, I would still have it assigned to me... That's what I get for being greedy on factors.

31 digits, if I counted correctly. My largest ever is 39. I found it running an ECM. I find more larger factors with P-1 than any other test.

P-1 found a factor in stage #2, B1=765000, B2=13770000.
UID: Jwb52z/Clay, M99722053 has a factor: 10512338016344446590255974311 (P-1, B1=765000, B2=13770000),

93.086 bits.

[B]James Heinrich[/B] made these really easy to trim down.

P-1 found a factor in stage #2, B1=725000, B2=12506250.
UID: Jwb52z/Clay, M99840353 has a factor: 5932727665521459357484273 (P-1, B1=725000, B2=12506250),

M14085161 has a factor: 32832537809579740360129 (ECM curve 3, B1=51000, B2=5000000)

P-1 = 32832 537809 579740 360128 = 2^6 × 3 × 7 × 11 × 13 × 6599 × 1 837931 × 14 085161

Not that interesting at first glance. However, it appears that an earlier P-1 effort (from December 2001) should have found this factor: [URL="https://www.mersenne.org/report_exponent/?exp_lo=14085161&full=1"]M14085161[/URL]

This was for GPUto72. I rarely get anything this size from [I]mfaktc[/I].
