To find the greatest common factor (GCF) of 264 and 660, we first need to list the factors of each number. The factors of 264 are 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, and 264. The factors of 660 are 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, and 660. The GCF of 264 and 660 is the largest number that appears in both lists, which is 132.
Ascertain the prime factors of both numbers :- 660 = 2 x 2 x 3 x 5 x 11 1155 = 3 x 5 x 7 x 11 The only factors (other than 1) that both numbers have in common are 3, 5 and 11. The greatest common factor is therefore 3 x 5 x 11 = 165 165 is the GCF of 660 and 1155
2 x 2 x 3 x 5 x 17 = 1020
