12

Step-by-step explanation:

One way is

divide the larger number by the smaller

If the remainder is zero then the smaller number is the greatest common factor.

If not repeat with larger number and remainder

144 ÷ 60 = 2 remainder 24 ← remainder ≠ 0

60 ÷ 24 = 2 remainder 12 ← remainder ≠ 0

24 ÷ 12 = 2 remainder zero, thus

greatest common factor is 12
