Given Input Data is 638, 957, 569, 928

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

Prime Factorization of 638 is 2 x 11 x 29

Prime Factorization of 957 is 3 x 11 x 29

Prime Factorization of 569 is 569

Prime Factorization of 928 is 2 x 2 x 2 x 2 x 2 x 29

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(638, 957) = 1914

GCD(638, 957) = ( 638 x 957 ) / 1914

GCD(638, 957) = 610566 / 1914

GCD(638, 957) = 319

Step2:

Here we consider the GCD from the above i.e. 319 as first number and the next as 569

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

LCM(319, 569) = 181511

GCD(319, 569) = ( 319 x 569 ) / 181511

GCD(319, 569) = 181511 / 181511

GCD(319, 569) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 928

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

LCM(1, 928) = 928

GCD(1, 928) = ( 1 x 928 ) / 928

GCD(1, 928) = 928 / 928

GCD(1, 928) = 1

GCD of 638, 957, 569, 928 is 1
