The first one, I don't know but in the past 11.5 months I've found 17 factors
doing TF (Trial Factoring) 24/7 so on average 1 every 20 (24h) days using two PC's
so about 1 every 40 days for one PC. 1 Ghz PCs
If you do LL (LucasLehmer first time tests) then very nearly every time
you send in a result it is a composite, just don't know the factors,
only the extremely rare ones are Mersenne primes.
