M196876699 has a factor: 69856498528291506881

Might stick to TF instead of LL for now, CPU got over 90 degrees the other day testing M58378657

P-1 found a factor in stage #1, B1=545000.
M61464751 has a factor: 1304481738054358815443801
80.10 Bits; k = 10611624685946900 = 2 * 2 * 5 * 5 * 7 * 11 * 73 * 263 * 277 * 479 * 541

Very smooth, isn't it?

Factor found by TF but reported as P-1
 
I found this one by trial factoring on a GPU between 2[SUP]70[/SUP] and 2[SUP]71[/SUP] but it's been reported as P-1! Don't know why, when I uploaded the results file it said: not enough info to deduce how the factor was found, assuming the factor was found by P-1...

[QUOTE=Uncwilly;342603]Just improved my best:
[URL="http://www.mersenne.ca/exponent/62364539"]62,364,539[/URL] has a factor of 47534549460523374611238927191
95.26 bits[/QUOTE]Just improved my personal record:
63857267 has a factor of 156110319012514871033075941441
That is 96.979 bits.

2[SUP]5[/SUP] × 3 × 5 × 7 × 13 × 479 × 6047 × 23719 × 407321 somewhat smooth.

BTW, for James H:
For some reason my previous best does not show up in my list of personal best factors on Mersenne.ca

P-1 found a factor in stage #2, B1=580000, B2=10295000.
UID: Jwb52z/Clay, M65679853 has a factor: 1000168241953080713686576765228755592980941664515163463

This is my first composite factor that I know of now.

It breaks down into the following:
1. 1969854626018798635131313 - 25 80.704 bits
2. 507737083103682773755444370551 - 30 98.680 bits.
