Therefore, GCD of numbers 156, 656, 636, 671 is 1

Given Input Data is 156, 656, 636, 671

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

Prime Factorization of 156 is 2 x 2 x 3 x 13

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 671 is 11 x 61

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(156, 656) = 25584

GCD(156, 656) = ( 156 x 656 ) / 25584

GCD(156, 656) = 102336 / 25584

GCD(156, 656) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 636

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

LCM(4, 636) = 636

GCD(4, 636) = ( 4 x 636 ) / 636

GCD(4, 636) = 2544 / 636

GCD(4, 636) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 671

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

LCM(4, 671) = 2684

GCD(4, 671) = ( 4 x 671 ) / 2684

GCD(4, 671) = 2684 / 2684

GCD(4, 671) = 1

GCD of 156, 656, 636, 671 is 1
