Step-by-step explanation:

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 150 are: 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150

Then the greatest common factor is 30.

15 is not a prime number.

10 is not a prime number.

6 is not a prime number.

5 is a prime number.
