Given Input Data is 638, 568, 925, 581

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 568 is 2 x 2 x 2 x 71

Prime Factorization of 925 is 5 x 5 x 37

Prime Factorization of 581 is 7 x 83

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, 568) = 181192

GCD(638, 568) = ( 638 x 568 ) / 181192

GCD(638, 568) = 362384 / 181192

GCD(638, 568) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 925

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

LCM(2, 925) = 1850

GCD(2, 925) = ( 2 x 925 ) / 1850

GCD(2, 925) = 1850 / 1850

GCD(2, 925) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 581

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

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

GCD(1, 581) = 581 / 581

GCD(1, 581) = 1

GCD of 638, 568, 925, 581 is 1
