Given Input Data is 387, 222, 572, 493

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

Prime Factorization of 387 is 3 x 3 x 43

Prime Factorization of 222 is 2 x 3 x 37

Prime Factorization of 572 is 2 x 2 x 11 x 13

Prime Factorization of 493 is 17 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(387, 222) = 28638

GCD(387, 222) = ( 387 x 222 ) / 28638

GCD(387, 222) = 85914 / 28638

GCD(387, 222) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 572

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

LCM(3, 572) = 1716

GCD(3, 572) = ( 3 x 572 ) / 1716

GCD(3, 572) = 1716 / 1716

GCD(3, 572) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 493

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

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

GCD(1, 493) = 493 / 493

GCD(1, 493) = 1

GCD of 387, 222, 572, 493 is 1
