Given Input Data is 957, 203, 580, 628

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

Prime Factorization of 957 is 3 x 11 x 29

Prime Factorization of 203 is 7 x 29

Prime Factorization of 580 is 2 x 2 x 5 x 29

Prime Factorization of 628 is 2 x 2 x 157

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(957, 203) = 6699

GCD(957, 203) = ( 957 x 203 ) / 6699

GCD(957, 203) = 194271 / 6699

GCD(957, 203) = 29

Step2:

Here we consider the GCD from the above i.e. 29 as first number and the next as 580

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

LCM(29, 580) = 580

GCD(29, 580) = ( 29 x 580 ) / 580

GCD(29, 580) = 16820 / 580

GCD(29, 580) = 29

Step3:

Here we consider the GCD from the above i.e. 29 as first number and the next as 628

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

LCM(29, 628) = 18212

GCD(29, 628) = ( 29 x 628 ) / 18212

GCD(29, 628) = 18212 / 18212

GCD(29, 628) = 1

GCD of 957, 203, 580, 628 is 1
