Or 6 and 36, 5 and 30, and things like that. They aren't, right? A co prime is a pair of numbers whose greatest common factor is 1. They (7 and 49) share 7 as well as 1. If 7 and 49 aren't co prime, it will clear up a huge programming question.

They are not coprime. Their greatest common divisor is $7$, not $1$. – Rory Daulton Jun 30 '15 at 01:17

Nope they are not. $7$ is a common divisor!
