Found a factor during TF, common I know but what does it mean?

Here is the factor info:

Just curious as to how this helps the overall project or if it even does. I am not a math genius by any means.
Thanks!

Congrats. Now you know the associated Mersenne number is not prime, and you just saved having to do two expensive LL tests.

So the system automatically removes it from future work?

Yup.

Cool. I have an FX8350 doing TF and an I7-6700k running first time LL's. I figured one to help the project and one to look for the next big one. lol

You would get more out of the 8350 doing Double Check LL testing. CPUs are greatly outclassed by GPUs for TF, and doing it on a less efficient chip is even less desirable.

Don't get me wrong, I run AMD FX as well, doing DC. You might as well throw the higher power consumption of an FX (relative to Intel) at work which gets the most out of it. Besides, there is still the chance that DC will turn up the next Mersenne Prime.

All work contributes to the project. It's just that some hardware does better at certain types of work.

If you enjoy searching for factors and your AMD machine has a suitable (read: 4+ GB) amount of memory, you might consider putting it to P-1 work.

Excellent point!
