To find this, you first have to split the numbers into their prime factors:

18 = 2x3x3

54 = 2x3x3x3

The next step is to identify any common prime factors. In this case both numbers have a 2 and two 3s as prime factors. Multiply these together gives you:

2x3x3 = 18

Therefore the HCF of 18 and 54 is 18.
