Those were both logged in the 2 PM local (America/Chicago) hour Sunday, while I was sleeping (I didn't wake up until after 7 PM local Sunday night). Less than 11 hours later, just after 1 AM local Monday, I beat my personal best again:

275190978175938200476768961501749313 for M5211289 (B1=2,500,000, B2=240,000,000) (117.728 bits)

Sadly, no bonus P+1 hit for this one.

M6282557 has a 112.036-bit (34-digit) factor: 5324115842154238964583982961636201 (P-1,B1=3000000,B2=90000000)


Quite nice one, and first found in that range for me.

My CPUs have mostly been busy doing other stuff for months, so I was mildly excited to see my first P-1 factor since June:
M105233789 has a 92.789-bit (28-digit) factor: 8554126736286122188536749441 (P-1,B1=820000,B2=34707000)
Only to discover it had been lingering in worktodo for too long and had apparently expired and someone else found the factor two weeks ago.

Ah, didn't know. Can you edit my message? (And add that there will be 1,830,XXX,XXX numbers too)

Everything on mersenne.org should show up on mersenne.ca, albeit after a delay of up to 24.5h -- new factors are pulled in every hour (from recent cleared report), whereas the detailed work information (who what when how) is pulled in every night about 00:30h UTC.

A related warning: exponent pages on mersenne.ca are heavily cached, if you look at the page after the factor is discovered but before the full nightly sync, subsequent page views may not show the full details, but Ctrl-F5 forcible refresh will fix that.

https://www.mersenne.ca/json2bbcode.php may be useful to you in formatting results to post in this thread with automatic linking to both mersenne.org and mersenne.ca (and bit size).

Dylan found a nice composite:
M4900289 has a 197.901-bit (60-digit) composite (P30+P31) factor: 375214712823873127465912884273993479895231432491081329619849 (P-1,B1=2350000,B2=213850000)

Today, for the first time ever, my machine found a composite factor composed of three factors, of an exponent trial factored to 71 bits:

https://www.mersenne.ca/exponent/9141029

Just before, in the morning it found a 114 bits factor ranking 12th in my personal top 500 and two hours later a regular 92 bits factor.

P-1 found a factor in stage #1, B1=763000.
UID: Jwb52z/Clay, M106358779 has a factor: 282917789511750372931085031635362975391 (P-1, B1=763000),

I think this might be my biggest factor, ever!

127.734 bits!
