Given Input Data is 627, 220, 656, 997

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 627 is 3 x 11 x 19

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 997 is 997

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(627, 220) = 12540

GCD(627, 220) = ( 627 x 220 ) / 12540

GCD(627, 220) = 137940 / 12540

GCD(627, 220) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 656

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(11, 656) = 7216

GCD(11, 656) = ( 11 x 656 ) / 7216

GCD(11, 656) = 7216 / 7216

GCD(11, 656) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 997

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 997) = 997

GCD(1, 997) = ( 1 x 997 ) / 997

GCD(1, 997) = 997 / 997

GCD(1, 997) = 1

GCD of 627, 220, 656, 997 is 1
