What is the greatest common factor of 120 and 135?

Answer 1

To find the greatest common factor (GCF) of 120 and 135, we need to determine the largest number that divides both 120 and 135 without leaving a remainder. One way to find the GCF is to list the factors of each number and identify the greatest one they have in common. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. The factors of 135 are 1, 3, 5, 9, 15, 27, 45, and 135. The greatest common factor of 120 and 135 is 15.

Answer 2

The GCF is 15 because it is the highest number that will divide exactly into 135 and 120 leaving no remainders.
