UID: storm5510/7700_Kaby_Lake, M7755521 has a factor: 105137409539055148931876353 (P-1, B1=370000, B2=8140000, E=6)

86.442 bits.

This is not a record here, or for me. However, it is the first I have found of any significance is a really long time.

From gpuOwl:

{"status":"F", "exponent":"7765781", "...":"PM1", "B1":"370000", "B2":"8140000", "...", "factors":["140468706376328182650630225863",...}
96.826 bits.

{"status":"F", "exponent":"7766881", "...":"PM1", "B1":"370000", "B2":"8140000", "...", "factors":["14786058658810602089190892018393"...}
103.544 bits.

I shortened these a little for readability.

The exponent has previously had a total about 60% of a first time check run (3 different users). What a waste of cycles when a factor was so close. I have done 7 different single bit factoring runs on this exponent (2009, 2012, 2014, 2014, 2015, 2017, 2020)

If the exponent would have received proper P-1'ing with stage 2, the same factor would long have been found, even barely with the lower GPU72 bounds.

Does this make it simpler? Now with sortable columns for exponent/bits/date.

OliverRyan must be too modestbusy to mention this one:
3307 has (another factor)
3413215452475967590824666626325289455333796024133147903 181.1 bits Found on April 17July 19.


The kicker is that the remaining cofactor is......
a PRP prime.
Here it is in all of its 895 digits of glory

Dario's ECM site confirms it.

That's because Ryan found it, I only appear in another result line (if you were thinking about me).

Wow! That is a lot simpler. Some of the older programs, like CUDAPm1 and CUDALucas could migrate to JSON. On the other hand is gpuOwl. It does those jobs and generates JSON. Perhaps there is no point in update the older ones after-all. mfaktc would be a good candidate though. Just some ideas...
