Question

Select the GCF of these numbers.

48 and 60

Answer 1

GCF of 48 and 60 is 12

Answer 2

Solution:

The GCF of 48 and 60 is 12.

Explanation:

We have been given the numbers 48 and 60.

First of all we write the prime factorization of these numbers.

$48 = 2\times 2 \times 2 \times 2 \times 2 \times 3\\60 = 2\times 2 \times 3 \times 5$

GCF is greatest common factors and we find by taking the multiplication of the common numbers in the prime factorization.

The multiplication of the common numbers in the above prime factorization is

$2 \times 2 \times 3 =12$

Hence, the GCF of 48 and 60 is 12.
