9 (factors 1, 3, and 9) and 10 (factors 1, 2, 5, and 10) are coprime numbers. Numbers are coprime (also called relatively prime) if 1 is their only common factor.

coprime numbers with 18 are : 17 and 19.

The least common multiple of two numbers is the product of those two numbers divided by their greatest common factor. It the two numbers are coprime (or relatively prime), their greatest common factor is 1. Therefore, their least common multiple is a x b ÷ GCF (of a and b) = a x b ÷ 1 = a x b. The least common multiple of two coprime numbers is the numbers multiplied together.
