What is the greatest common factor of 18 and 48?

Answer 1

The GCF of 18 and 48 is 6.

The factors of 18 are 1, 2, 3, 6, 9, and 18.

The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

The common factors are 1, 2, 3, and 6. Therefore, 6 is the greatest common factor.

The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.

The prime factors of 18 are 2, 3, and 3.

The prime factors of 48 are 2, 2, 2, 2, and 3.

The common prime factors are 2 and 3, so the greatest common factor is 2 x 3 = 6.
Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Factors of 18: 1, 2, 3, 6, 9, 18

GCF (48, 18) = 6

Answer 2

There is only one common factor, not several.The greatest common factor of 48 and 18 is the same as the greatest common factor of 18 and 12, where 12 is the remainder of the division of 48 by 18. (This is the beginning of Euclid's algorithm.)
