[QUOTE=alpertron;603543]I'm working on the range 18.8M, but for several days there was no factorization:


I'm using Prime version 30.8 build 13.[/QUOTE]

Been there....sometimes our only luck is bad luck.... it always turns around.

With your good bounds it shouldn't be long.

Sorry... It looks like my Colab P-1'ers "took" your factors; they found four (4#) in the last 24 hours. LOL...

As Wayne said, it can be frustrating, but this is how statistics work. You are still well within the expected success rate; you shouldn't /yet/ distrust your hardware (nor the code).

Tangentially... Can anyone delegate to me another 0.01M range to give to the Colab crew? We're almost done with everything reserved in 18.84M.

I found two new factors, so everything (software and hardware) is OK:

[code]
Manual testing 18871889 F-PM1 2022-04-09 12:39 0.0 Factor: 409345190904906788363497 / (P-1, B1=1000000, B2=500458530) 29.8282
Manual testing 18871781 F-PM1 2022-04-09 04:02 0.0 Factor: 37910134458016135088804897239 / (P-1, B1=1000000) 0.9173
[/code]

Under 100!!! Woot Woot
 
99 more factors in 8 ranges; 5 are 8 or less and the max is 36.

chalsall 2022-04-09 22:43

Ranges Remaining: 7. Factors to Find: 83.

Both prime numbers... :smile:

Zhangrc 2022-04-10 02:42

And 108.9M too, it needs only 2 more factors!
But it should be done anyway before the project finishes.

alpertron 2022-04-10 23:35

With the new factor of M18868373, the range 18.8M is finally below 2000.

Excellent. I'm going to bow out here. Good luck with the finish and many thanks for the project!

Thanks a lot ... the next project might be calling your name. :grin:

I mean all of you: masser, SethTro, Alpertron, Luminescence, and other names not on the tip of my tongue right now.

You are all appreciated and all welcome to move to project next.
