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.

What fraction is equivalent to 42 63?
42/63= 2/3. Look for common factors. You can express 42 as 6 x 7 You can express 63 as 9 x 7 Divide by the common factor of 7, and you get 6/9 6 can be expressed as 2 x 3 9 can be expressed as 3 x 3 Divide by the common factor of 3 and you get 2/3 There are no more common factors, so thats your answer. If you're smart, you'd see that 21 was a common factor too, taking you straight to 2/3, but in general, its simpler to find and use smaller factors and repeat the process until there are no more factors.
