Default Biggest factors found by P-1

I was going through some of my P-1 results and had to :facepalm: when I saw that the latest two were 274.09 and 274.18.

Anyway, I found this one too. M63267157 has a factor: 91234295579487063953720150647 = 296.204

Trial factoring to 97 in order to find that one would take 251658240 GHz-Days which is over a hundred times the yearly output of GPU72 in TF. Woohoo P-1 factoring.


I'm sure 296.204 isn't actually such a big deal, so I was wondering if everyone could dig through their results for the biggest factor they've found by P-1. (in your personal results page, just look for the result that just fits in the column: that one is the biggest and determines the size of the column) Let's see who takes home the prize.

At least on GPU72, the winner is TheJudger, at 2146.45.

How many people do P-1 through GPU72 versus primenet? Is there any strong reason to pick one over the other?

Impossible for me to tell.

Not really, other than the "pretty graphs".

Almost everyone who uses gpu72 for their gpu uses it for their "other" stuff as well.

The overall winner I think is this one:

I was in position #1 for a long time with 2131.28, but have since been bumped down 3 places. You don't even make GPU72s top 100 with less than 2107 anymore.

Are the big ones from setting bounds to freakishly high numbers or just random luck?

All of mine are random luck, and I have four on the GPU72 top 100 list (I do give P-1 8000 Mb memory).

Is P-1 guaranteed to give a prime factor? Could some of those massive ones be products of two smaller numbers around 274 to 276 or whatever to give 2150? Just thought of that now.
