Given Input Data is 645, 444, 418, 951

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

Prime Factorization of 645 is 3 x 5 x 43

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

Prime Factorization of 418 is 2 x 11 x 19

Prime Factorization of 951 is 3 x 317

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(645, 444) = 95460

GCD(645, 444) = ( 645 x 444 ) / 95460

GCD(645, 444) = 286380 / 95460

GCD(645, 444) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 418

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

LCM(3, 418) = 1254

GCD(3, 418) = ( 3 x 418 ) / 1254

GCD(3, 418) = 1254 / 1254

GCD(3, 418) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 951

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

LCM(1, 951) = 951

GCD(1, 951) = ( 1 x 951 ) / 951

GCD(1, 951) = 951 / 951

GCD(1, 951) = 1

GCD of 645, 444, 418, 951 is 1
