Given Input Data is 129, 675, 839

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 675 is 3 x 3 x 3 x 5 x 5

Prime Factorization of 839 is 839

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, 675) = 29025

GCD(129, 675) = ( 129 x 675 ) / 29025

GCD(129, 675) = 87075 / 29025

GCD(129, 675) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 839

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

LCM(3, 839) = 2517

GCD(3, 839) = ( 3 x 839 ) / 2517

GCD(3, 839) = 2517 / 2517

GCD(3, 839) = 1

GCD of 129, 675, 839 is 1
