The LCM of prime numbers is simply their product (a x b, or x*y).

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of two prime numbers is 1. Therefore, the least common multiple of two prime numbers is the two numbers multiplied together, since dividing by 1 will not change the answer.

The same applies to "relatively prime" numbers such as 10 and 21, where the GCF is also 1.
