Given Input Data is 728, 808, 321

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

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

Prime Factorization of 808 is 2 x 2 x 2 x 101

Prime Factorization of 321 is 3 x 107

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(728, 808) = 73528

GCD(728, 808) = ( 728 x 808 ) / 73528

GCD(728, 808) = 588224 / 73528

GCD(728, 808) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 321

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

LCM(8, 321) = 2568

GCD(8, 321) = ( 8 x 321 ) / 2568

GCD(8, 321) = 2568 / 2568

GCD(8, 321) = 1

GCD of 728, 808, 321 is 1
