Given Input Data is 725, 638, 571, 137

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

Prime Factorization of 725 is 5 x 5 x 29

Prime Factorization of 638 is 2 x 11 x 29

Prime Factorization of 571 is 571

Prime Factorization of 137 is 137

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(725, 638) = 15950

GCD(725, 638) = ( 725 x 638 ) / 15950

GCD(725, 638) = 462550 / 15950

GCD(725, 638) = 29

Step2:

Here we consider the GCD from the above i.e. 29 as first number and the next as 571

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

LCM(29, 571) = 16559

GCD(29, 571) = ( 29 x 571 ) / 16559

GCD(29, 571) = 16559 / 16559

GCD(29, 571) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 137

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

LCM(1, 137) = 137

GCD(1, 137) = ( 1 x 137 ) / 137

GCD(1, 137) = 137 / 137

GCD(1, 137) = 1

GCD of 725, 638, 571, 137 is 1
