Given Input Data is 642, 250, 246, 711

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

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 250 is 2 x 5 x 5 x 5

Prime Factorization of 246 is 2 x 3 x 41

Prime Factorization of 711 is 3 x 3 x 79

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(642, 250) = 80250

GCD(642, 250) = ( 642 x 250 ) / 80250

GCD(642, 250) = 160500 / 80250

GCD(642, 250) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 246

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

LCM(2, 246) = 246

GCD(2, 246) = ( 2 x 246 ) / 246

GCD(2, 246) = 492 / 246

GCD(2, 246) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 711

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

LCM(2, 711) = 1422

GCD(2, 711) = ( 2 x 711 ) / 1422

GCD(2, 711) = 1422 / 1422

GCD(2, 711) = 1

GCD of 642, 250, 246, 711 is 1
