M6282557 has a 112.036bit (34digit) factor: 5324115842154238964583982961636201 (P1,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 P1 factor since June:
M105233789 has a 92.789bit (28digit) factor: 8554126736286122188536749441 (P1,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.

Disclaimer: You may not see these in mersenne.ca, but this is probably because I self assigned them.

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

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 CtrlF5 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).

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.
