If gcd("a", "b") = 1, then "a" and "b" are said to be coprime (or relatively prime). This property does not imply that "a" or "b" are themselves prime numbers. For example, neither 6 nor 35 is a prime number, since they both have two prime factors: 6 = 2 × 3 and 35 = 5 × 7. Nevertheless, 6 and 35 are coprime. No natural number other than 1 divides both 6 and 35, since they have no prime factors in common.
