Given Input Data is 129, 636, 847

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 847 is 7 x 11 x 11

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(129, 636) = 27348

GCD(129, 636) = ( 129 x 636 ) / 27348

GCD(129, 636) = 82044 / 27348

GCD(129, 636) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 847

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

LCM(3, 847) = 2541

GCD(3, 847) = ( 3 x 847 ) / 2541

GCD(3, 847) = 2541 / 2541

GCD(3, 847) = 1

GCD of 129, 636, 847 is 1
