Given Input Data is 956, 868, 663, 355

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

Prime Factorization of 956 is 2 x 2 x 239

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 355 is 5 x 71

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(956, 868) = 207452

GCD(956, 868) = ( 956 x 868 ) / 207452

GCD(956, 868) = 829808 / 207452

GCD(956, 868) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 663

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

LCM(4, 663) = 2652

GCD(4, 663) = ( 4 x 663 ) / 2652

GCD(4, 663) = 2652 / 2652

GCD(4, 663) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 355

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

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

GCD(1, 355) = 355 / 355

GCD(1, 355) = 1

GCD of 956, 868, 663, 355 is 1
