Given Input Data is 644, 956, 797, 497

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

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 956 is 2 x 2 x 239

Prime Factorization of 797 is 797

Prime Factorization of 497 is 7 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(644, 956) = 153916

GCD(644, 956) = ( 644 x 956 ) / 153916

GCD(644, 956) = 615664 / 153916

GCD(644, 956) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 797

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

LCM(4, 797) = 3188

GCD(4, 797) = ( 4 x 797 ) / 3188

GCD(4, 797) = 3188 / 3188

GCD(4, 797) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 497

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

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

GCD(1, 497) = 497 / 497

GCD(1, 497) = 1

GCD of 644, 956, 797, 497 is 1
