To find the highest/greatest common factor. you must first identify the factors for each number.For 120, its factors are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.For 36, its factors are 1, 2, 3, 4, 9, 12, 18, and 36.12 is the highest (or greatest) factor they have in common, so the HCF for 120 and 36 is 12.
factors of 16 are: 1, 2, 4, 8, and 16.factors of 40 are 1, 2, 4, 5, 8, 10, and 20.factors of 56 are 1, 2, 4, 7, 8, 14, 28 and 56.common factors: 1,2,4, and 8.greatest of the common factors: 8.GCF of 16 40 and 56 = 8
