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 40, 60, and 90 is 10
The GCF of 40 and 60 is 20 Additional Details The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The common factors are 1, 2, 4, 5, 10, and 20. Therefore, 20 is the greatest common factor. The greatest common factor can also be determined from the prime factors. The prime factors of 40 are 2, 2, 2, and 5. The prime factors of 60 are 2, 2, 3, and 5. The prime factors they have in common are 2, 2, and 5, so the greatest common factor is 2 x 2 x 5 = 20.
