To find all the factors of a number, it helps to break the number down into its prime factors first. 240 ends in 0, so obviously has 2 and 5 as prime factors. Divide it by 10 and we get 24, which is known to be 4x6 from times tables. Thus the prime factors of 240 are 2, 2, 2, 2, 3 and 5. To find all the other factors (other than 1 and itself) you simply multiply any combination of these prime factors together. Therefore the factors of 240 are:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120 and 240.
