Given Input Data is 256, 216, 115, 422

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

Prime Factorization of 256 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 115 is 5 x 23

Prime Factorization of 422 is 2 x 211

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(256, 216) = 6912

GCD(256, 216) = ( 256 x 216 ) / 6912

GCD(256, 216) = 55296 / 6912

GCD(256, 216) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 115

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

LCM(8, 115) = 920

GCD(8, 115) = ( 8 x 115 ) / 920

GCD(8, 115) = 920 / 920

GCD(8, 115) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 422

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

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

GCD(1, 422) = 422 / 422

GCD(1, 422) = 1

GCD of 256, 216, 115, 422 is 1
