Find the gcf of 36 and 54

Problem. Find the greatest common factor of 36 and 54.

Solution.

See How to find the greatest common factor of two numbers?

The prime factorization of 36

36 =
2 * 2 * 3 * 3

See 36 prime factorization.

The prime factorization of 54

54 =
2 * 3 * 3 * 3

See 54 prime factorization.

Find the common prime factors of these two numbers 36 and 54

36 –> (2, 2, 3, 3)
54 –> (2, 3, 3, 3)

The common factors of 36 and 54 are

2, 3, 3

The product of these common prime factors is the greatest common factor of 36 and 54

2 * 3 * 3 = 18
