Given Input Data is 256, 356, 557

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 356 is 2 x 2 x 89

Prime Factorization of 557 is 557

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, 356) = 22784

GCD(256, 356) = ( 256 x 356 ) / 22784

GCD(256, 356) = 91136 / 22784

GCD(256, 356) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 557

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

LCM(4, 557) = 2228

GCD(4, 557) = ( 4 x 557 ) / 2228

GCD(4, 557) = 2228 / 2228

GCD(4, 557) = 1

GCD of 256, 356, 557 is 1
