The greatest factor of any positive number is the number itself.
This is tricky. Once you determine that 73 is a prime number then you can ignore 127 (since 73 is not a factor of 127). So, the greatest common factor is 1. Note: if you asked 73 and 146 then the answer would be 73. Anytime one of the numbers is a prime - then the answer is EITHER 1 or the prime number (if the other number is a multiple of the prime).
