Problem

Find the greatest common factor for following numbers 72 and 96.

2

Hint

Finding the greatest common factor (GCF) of two numbers involves determining the largest number that divides both numbers without leaving a remainder.

3

Step

Let’s find the GCF of 72 and 96 using a step-by-step process:

4

Step

Factors of 72:

1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

5

Step

Factors of 96:

1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

6

Step

Common factors of 72 and 96 are

1, 2, 3, 4, 6, 8, 12, 24

7

Step

The greatest common factor (GCF) of 72 and 96 is 24, as it’s the largest number that divides both 72 and 96 without leaving a remainder.

8

Step

So, the greatest common factor of 72 and 96 is

24
