Do we know anything else about this number? It's the product of two large primes, right? Or possibly more than that?? I remember looking one other time for a list of large primes without much success. But I guess if such lists existed, this sort of problem wouldn't be very insteresting, would it? And determining primes isn't exactly a quick science either from what I understand. Heh, it's not divisible by 2 or 3... And the last digits would be 1 & 3 or 7 & 9 if only two multiplicands. That should narrow it down enough for you guys. :) More seriously, perhaps a distributed computing effort like the RSA/DES challenges or SETI would work? Break the keyspace up into all numbers between 1 and that whole thing that end in 1 & 3 or 7 & 9, and let people try multiplying all those numbers until SOMEONE finds it. Might be a nice RGVC project, assuming the keyspace splitter and calculator server & client aren't too hard to program...
