The greatest common factor of 15 and 40 is 5

The GCF is 5.

The GCF is... 1! 1 is the only factor common to all three numbers.

To find the greatest common factor of two numbers, you first need to break them into their prime factors: 15 = 3x5 40 = 2x2x2x5 The next step is to identify any common factors. In this case, the only common factor is 5. Thus, the greatest common divisor of the numbers 15 and 40 is 5.
