If the greatest common factor of two or more numbers is 1, then they are

relatively prime.

Greatest common factor (GCF) is a number that is greatest among the

common factors of the numbers.

List the factors of each number.

Factors of 18: 2, 3, 6, 9, 18

Factors of 33: 3, 11, ,33

Identify the greatest common factor.

The greatest common factor of 18 and 33 is 3.

Since the GCF is not 1, 18 and 33 are not relatively prime.

The greatest common factor of 18 and 33 is 3.

18 and 33 are not relatively prime.
