The HCF (highest common factor) is found by splitting each number into its prime factors:
- 36 = 2 x 2 x 3 x 3
- 54 = 2 x 3 x 3 x 3
- 72 = 2 x 2 x 2 x 3 x 3
The HCF is then found by mulitplying together the factors that are common to each number:
2 x 3 x 3 = 18
(Because there is only one 2 in 54, only one 2 can be used. The same applies with the number o 3's. There are only two in each number so only 2 can be used).
