Question

Each answer choice is a factor pair of 60

60
.

Which factor pair contains only composite numbers?

Answer 1

60 is a composite number, that has twelve factors. They are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.

Step-by-step explanation:

Answer 2

The factor pair 4 x 15 contains only composite numbers.

Step-by-step explanation:

A composite number is a number that has factors other than 1 and itself. To determine if a factor pair contains only composite numbers, we need to check if both numbers in the pair are composite. Let's find the factor pairs of 60:

1 x 60 = 60

2 x 30 = 60

3 x 20 = 60

4 x 15 = 60

5 x 12 = 60

6 x 10 = 60

Out of these factor pairs, only the pair 4 x 15 contains two composite numbers (4 and 15). So the factor pair 4 x 15 contains only composite numbers.
