First you find the prime factors
275=5*5*11
605=5*11*11
So the greatest common factor is 5*11=55

The answer is 55. 605/55=11 & 275/55=5

Find the prime factors of each number.
275
= 5 x 55
= 5^2 x 11.
605
= 5 x 121
= 5 x 11^2.
The only prime numbers in the factors are 5 and 11. The highest power of 5 common to both numbers is 1. The highest power of 11 common to both is 1.
The GCF is therefore 5^1 x 11^1 = 5 x 11 = 55.

It would be 55.
275 / 55 = 5
605 / 55 = 11
This is the largest common factor since the answers of the equations above are both prime, so you can't go any further.
