Given Input Data is 729, 291, 577, 855

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

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

Prime Factorization of 291 is 3 x 97

Prime Factorization of 577 is 577

Prime Factorization of 855 is 3 x 3 x 5 x 19

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(729, 291) = 70713

GCD(729, 291) = ( 729 x 291 ) / 70713

GCD(729, 291) = 212139 / 70713

GCD(729, 291) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 577

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

LCM(3, 577) = 1731

GCD(3, 577) = ( 3 x 577 ) / 1731

GCD(3, 577) = 1731 / 1731

GCD(3, 577) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 855

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

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

GCD(1, 855) = 855 / 855

GCD(1, 855) = 1

GCD of 729, 291, 577, 855 is 1
