Given Input Data is 864, 556, 256

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

Prime Factorization of 864 is 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 556 is 2 x 2 x 139

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

Highest common occurrences in the given inputs are 2²

Multiplying them we get the GCD as 4

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(864, 556) = 120096

GCD(864, 556) = ( 864 x 556 ) / 120096

GCD(864, 556) = 480384 / 120096

GCD(864, 556) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 256

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

LCM(4, 256) = 256

GCD(4, 256) = ( 4 x 256 ) / 256

GCD(4, 256) = 1024 / 256

GCD(4, 256) = 4

GCD of 864, 556, 256 is 4
