fond of a factor? Turn yourself in to become inane - Page 79

Good, that´s a start!.
On another note, I reckon you´ve abandoned your quest for "monster factors". Is that so?

Hi,

just an hour ago "I" found this gem:

P-1 found a factor in stage #2, B1=620000, B2=12710000, E=12.
M67825453 has a factor: 1722206812177416217749744344545878167459479 (140.30 bits)
k = 12695874011909778308076647453765463 = 3 * 17 * 29 * 79 * 1447 * 24481 * 31039 * 349529 * 378277 * 747427

Should be my second largest P-1 factor so far.

Yup!

P.S. Where do you get those wonderful toys?

Hi Chris,

I can't be sure because I did P-1 factoring before you started GPUto72. But I'm pretty sure that it IS actually my 2nd biggest P-1 factor. I had 13x bit factor(s) before GPUto72 but I can't remember any factors above 2¹⁴⁰.

I get them from here.

A small shop with good prices and nice sales persons. And when you buy several exponents at once they grant you at small extra discount.

I got one today:

Code:

ECM found a factor in curve #2, stage #2
Sigma=7053813379423454, B1=3000000, B2=300000000.
UID: ANONYMOUS, M27529 has a factor: 9662183525912193406922912529583 (ECM curve 2, B1=3000000, B2=300000000)

k = 3 * 31^2 * 433 * 6988773391 * 20115060971

This k is quite rough.

I have just begun this quest ...

lycorn · 2014-07-23, 10:45

Wow, that´s a really nice one!
But you´ve not reported it yet, did you? It doesn´t appear as Factored, on Primenet pages.

PageFault · 2014-07-24, 00:22

The reason is that the manual results page won't accept it. George has been advised. There will be more of these. It takes quite a few curves, somewhere in the order of 6 to 7 thousand, should I count them. No biggie, just takes time and in time I'll move this onto all cores. At 15 000 curves per week, I should find a bunch of these.

Crunch on folks, happy hunting!

I don´t see any reason why that should happen, apart from the periodic glitches experienced by Primenet. Try resubmitting the result, as you may happen to have tried during a Primenet outage. They´ve been rather frequent lately, unfortunately.

An interesting one came up today:

Code:

ECM found a factor in curve #306, stage #2
Sigma=563592846122112, B1=11000000, B2=1100000000.
UID: ANONYMOUS, M25849 has a factor: 490089625697694370568455713655482757513

k = 2^2 * 3 * 179 * 271 * 208274569 * 78191933955159820247

k is just a bit rough.

5100 curves at a lower bound and 306 at the current bound and I came in just below the bound! I wonder how long until I work through to the next bound ...

TheJudger · 2014-11-16, 16:56

in contrast to your rough ks I've some smoothies here:

Code:

M70458881 has a factor: 178367954294318192443201
  77.23 Bits; k = 1265759204253600 = 2 * 2 * 2 * 2 * 2 * 3 * 5 * 5 * 7 * 113 * 227 * 383 * 7669
M76021597 has a factor: 21929119114257579600162546577
  94.14 Bits; k = 144229534629860377704 = 2 * 2 * 2 * 3 * 103 * 971 * 1973 * 2161 * 3257 * 4327

Those are very smooth, nice finds. I assume they are P-1, Stage 1 factors? I have one from a few years back, somewhere in a backup.

I'm seeing my ECM finds to be all rough, although my data is lacking.

Crunch on, happy hunting!
