Recently hit 100k in the project, got my bronze PPS sieve bronze badge, moved into the top 100 on the team as well but still a long way to the top. Working on PPS LLR and SGS badges as well _________________

Thanks guys. No primes yet Wabbit, but I have found 101 factors from the sieving so far _________________

So 101 numbers that could be, or not be, primes.

Factors are smaller numbers that fit into other number, alas not a prime. Sieving will never prove a prime, it just removes some of the non-primes so the LLR tests are a little more efficient. A sieve file has multiple numbers in it (say 100), so if you find 10 factors on that sieve it means 10 numbers of that list were eliminated from being tested on LLR.
I also have a few Prime brags, but I'll not steal someone else's post.
Congrats on the shrubbing you have accomplished so far. _________________ Watch the movie about me The 4-1-4s: The Original Teenage Hackers (It is only about 12 minutes long.)
My lucky numbers are 121*2^4553899-1 and 3756801695685*2^666669±1
