An integer greater than one is called a prime number if its only positive divisors (factors) are one and itself. For example, the prime divisors of 10 are 2 and 5; and the first six primes are 2, 3, 5, 7, 11 and 13

Why not 1 when it can be divided by 1 and 1 LOL

Hmm, interesting link. I just had to write a prime number generator for my c programming course, and I was wondering why 1 wasn't considered a prime. I had another problem though...writing a (reasonably fast) algorithm that calculates 2 as a prime is pretty damn tough too. Actually, I never did figure out how to include 2 in it either.

Bleh, I said reasonably fast . ;)

That one calculates the first 100,000 primes on a 500mhz processor in 56 minutes. Mine can calculate the first 100,000 (minus 2) primes in about 1 or 2 minutes on a 500mhz celeron.

VB sucks arse. :)
