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.
