Nice. Huge one.[/QUOTE]That's the [url=https://www.mersenne.ca/userfactors/pm1/1/bits]secondbiggest P1 factor[/url] ever! :bow wave:

:bow wave:[/QUOTE] I just noticed.:jvang: I was just getting a little frustrated with this range. Not alot of factors overall

Nice. Huge one.[/QUOTE] Well done. Very smooth too! 
How was this missed by firejuggler?

K=2^3 × 3 × 17 × 43 × 349 × 2393 × 2827673 This is in no way a criticism of firejuggler but a question about the reliability of either the software or hardware.

hmmm here is my mE632711 file to see if there was any problem. It was the first 14.6M exponent I did.
I just redid it and I found the factor. 
there is about 30 NF pm1 with the b1=800k and b2=179434710.
I'll rerun them 
[QUOTE=firejuggler;601843]there is about 30 NF pm1 with the b1=800k and b2=179434710.
I'll rerun them[/QUOTE] You may not have to . I have a computer that due to a cranial malfunction is running P1 in 14.6. I've already redone a few of your 800000s. I'm away for 12 more days so I can't stop it unless I can talk my son into it. 
Thank you. I'll let your computer do the job.

I've found three 100+ bits factors yesterday! (the first one is the biggest one I've found so far :smile:) Out of a total of 6 factors found yesterday in this range, and 4 so far today.
108.509 bits 461809633522436002942667757126991 105.164 bits 45433175071599793822345482321409 and 101.612 bits 3876227996028611127615928931137
