The first step in finding the greatest common factor is to break the numbers down into their prime factors:
663=3x13x17
1547=7x13x17
The next step is to identify any common factors. In this case, the common prime factors are 13 and 17. To find the greatest common factor we multiply these together:
13x17=221
So 221 is the GCF of 663 and 1547.
