Given Input Data is 684, 256, 557, 411

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

Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19

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

Prime Factorization of 557 is 557

Prime Factorization of 411 is 3 x 137

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(684, 256) = 43776

GCD(684, 256) = ( 684 x 256 ) / 43776

GCD(684, 256) = 175104 / 43776

GCD(684, 256) = 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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 411

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

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

GCD(1, 411) = 411 / 411

GCD(1, 411) = 1

GCD of 684, 256, 557, 411 is 1
