What is the greatest common factor of 30 42 and 48?

Answer 1

The GCF of 30, 42, and 48 is 6.

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30.

Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42.

Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.

GCF (30, 42, 48) = 6

Answer 2

To find the greatest common factor (GCF) of 30, 42, and 48, we first need to find the prime factorization of each number. The prime factorization of 30 is 2 x 3 x 5, 42 is 2 x 3 x 7, and 48 is 2 x 2 x 2 x 2 x 3. To find the GCF, we look for the common prime factors among the numbers, which are 2 and 3. The GCF of 30, 42, and 48 is the product of these common prime factors, which is 2 x 3 = 6.
