Given Input Data is 856, 321, 39, 478

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

Prime Factorization of 856 is 2 x 2 x 2 x 107

Prime Factorization of 321 is 3 x 107

Prime Factorization of 39 is 3 x 13

Prime Factorization of 478 is 2 x 239

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(856, 321) = 2568

GCD(856, 321) = ( 856 x 321 ) / 2568

GCD(856, 321) = 274776 / 2568

GCD(856, 321) = 107

Step2:

Here we consider the GCD from the above i.e. 107 as first number and the next as 39

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

LCM(107, 39) = 4173

GCD(107, 39) = ( 107 x 39 ) / 4173

GCD(107, 39) = 4173 / 4173

GCD(107, 39) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 478

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

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

GCD(1, 478) = 478 / 478

GCD(1, 478) = 1

GCD of 856, 321, 39, 478 is 1
