To find the greatest common factor (GCF) of 40, 60, and 90, you need to determine the largest number that divides evenly into all three numbers. First, list the factors of each number: 40 (1, 2, 4, 5, 8, 10, 20, 40), 60 (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60), and 90 (1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90). The GCF of 40, 60, and 90 is 10, as it is the largest number that is a factor of all three numbers.

What is the greatest common factor of 60 and 40?
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.
