Given Input Data is 286, 187, 444, 637

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

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 187 is 11 x 17

Prime Factorization of 444 is 2 x 2 x 3 x 37

Prime Factorization of 637 is 7 x 7 x 13

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(286, 187) = 4862

GCD(286, 187) = ( 286 x 187 ) / 4862

GCD(286, 187) = 53482 / 4862

GCD(286, 187) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 444

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

LCM(11, 444) = 4884

GCD(11, 444) = ( 11 x 444 ) / 4884

GCD(11, 444) = 4884 / 4884

GCD(11, 444) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 637

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

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

GCD(1, 637) = 637 / 637

GCD(1, 637) = 1

GCD of 286, 187, 444, 637 is 1
