Two numbers are "relatively prime" when they have no common factors other than 1.

In other words there is no value that you could divide them both by exactly (without any remainder).

Examples:

• 7 and 20 are relatively prime (no common factor)

• 6 and 20 are not relatively prime because you can evenly divide both by 2 (2 is a common factor)
