7/12 = 91/156 5/26 = 30/156 91- 30 = 61/156
7/12
It is: 7/12
The GCF is 13.
91 = 7 x 13 & 156 = 12 x 13, so 7/12 is the simplest form.
The GCF is 13.
91/156 = (7×13)/(12×13) = 7/12
65 + 91 = 156
The GCF is 13.
The GCF is 13.
The GCF is 13.The GCF is 13.
Multiples of 91:91 / 7 = 1391 / 13 = 77,13,91There really aren't any tricks here, just trial and errorSome multiples of 156:Because we already found the multiples of 91, and we know 156 isn't divisible by 91, let's try 13 (once again trial and error)156/13 = 122,12,13,156The answer is 13.
