To do this, you need to split the numbers into their prime factors:

18 = 2x3x3

12 = 2x2x3

The next step is to identify any common prime factors between the two numbers. In this case both numbers have a 2 and a 3 as prime factors. Multiply these together, and we get:

2x3 = 6. Therefore the HCF of 18 and 12 is 6.
