The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Then the greatest common factor is 12.
Answer: 12
Explanation:
36 = 2 x 2 x 3 x 3 = 2² x 3²
48 = 2 x 2 x 2 x 3 = 2³ x 3
60 = 2 x 2 x 3 x 5 = 2² x 3 x 5
Greatest Common Factors = 2² x 3 = 2 x 2 x 3 = 12
