What are the HCF of 54 and 96?

Answer 1

To work out the hcf of two numbers, you first need to break them down into their prime factors. In this case you'd get:

54 = 2x3x3x3

96 = 2x2x2x2x2x3

The next step is to identify any common prime factors. In this case, both numbers have a 2 and a 3 as prime factors. Multiply these together and you get 6. Therefore the HCF of 54 and 96 is 6.
