What is the greatest common factor of 150 and 180?

Answer 1

The Greatest Common Factor (GCF) of (150,180) is 30

150 = 2 x 3 x 5^2

180 = 2^2 x 3^2 x 5

gcf = 2 x 3 x 5 = 30

Answer 2

The least common factor is 1. (The least common factor of any two or more positive integers is always 1.)

Answer 3

Factors of 75: 1, 3, 5, 15, 25, 75.

Factors of 180: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180.
