What is the greatest common factor of 9 18 27 and 36?

Answer 1

The GCF of 9, 18, 27, and 36 is 9.

The prime factorization of 9 is 3*3

The prime factorization of 18 is 2*3*3

The prime factorization of 27 is 3*3*3

The prime factorization of 36 is 2*2*3*3

The GCF is 3*3 = 9

Answer 2

The greatest common factor (GCF) of a set of numbers is the largest number that divides evenly into all of the numbers in the set. To find the GCF of 9, 18, 27, and 36, we first need to find the factors of each number. The factors of 9 are 1, 3, and 9; the factors of 18 are 1, 2, 3, 6, 9, and 18; the factors of 27 are 1, 3, 9, and 27; and the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The largest number that is common to all sets of factors is 9, so the greatest common factor of 9, 18, 27, and 36 is 9.

Answer 3

The GCF is 3.

Answer 4

Their GCF is 9.
