Given Input Data is 876, 856, 729

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

Prime Factorization of 876 is 2 x 2 x 3 x 73

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

Prime Factorization of 729 is 3 x 3 x 3 x 3 x 3 x 3

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(876, 856) = 187464

GCD(876, 856) = ( 876 x 856 ) / 187464

GCD(876, 856) = 749856 / 187464

GCD(876, 856) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 729

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

LCM(4, 729) = 2916

GCD(4, 729) = ( 4 x 729 ) / 2916

GCD(4, 729) = 2916 / 2916

GCD(4, 729) = 1

GCD of 876, 856, 729 is 1
