Since the number is low, you could make a list of all numbers with a factor of 12 and pair up the ones that do not have higher common factors:
12
24
36
48
60
72
84
12 and 72
24 and 60
36 and 48
The actual formula is
a + b = 7 where a and b are integers -- 12 (a +b) = 84
b = [ (84 - 12a) ] / 12

Hcf of 7891156?
Commas are stripped from questions, so if you do not put spaces after commas, the result is a list of numbers becoming a single number. Based on the digits, I guess there were three numbers 78, 91, 156 whose HCF is 13.
What numbers relatively prime?
