To do this, the first step is to write the numbers as the product of their prime factors. In this case we have:
42 = 2x3x7
63 = 3x3x7
The next step is to identify common factors. In this case both numbers have a 3 and a 7 as factors. Take these numbers and multiply them together to find the HCF:
3x7 = 21
Thus the highest common factor of 42 and 63 is 21.
