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
We want the GCF or highest common factor of 15 and 24. The factors of 15 and 1,3, and 5.For 24 we have 1,3, 8, 12 and 24.Since 5 is not a factor of 24, the GCF or highest factor is 3
You need at least two numbers to find a GCF.
Factors of 26: 1, 2, 13, 26Factors of 39: 1, 3, 13, 39GCF (26, 39) = 13
The GCF of the numbers 24 and 4 would be 4. This is taught in math.
