What is the greatest common factor of 315 and 108?

Answer 1

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.

The greatest common factor of 150 and 315 is 15

Answer 2

The GCF of 108 and 150 is 6. Note that 6 goes into 108 sixteen times. Also, 6 goes into 150 twenty five times.

There is no greater common factor. You can see this by writing the numbers out as the product of their primes.

Answer 3

Since 108 is a factor of 324, it is automatically the GCF.

Answer 4

The GCF is 1.

Answer 5

GCF(108, 324) = 108.
