Given Input Data is 872, 580, 329, 847

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

Prime Factorization of 872 is 2 x 2 x 2 x 109

Prime Factorization of 580 is 2 x 2 x 5 x 29

Prime Factorization of 329 is 7 x 47

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(872, 580) = 126440

GCD(872, 580) = ( 872 x 580 ) / 126440

GCD(872, 580) = 505760 / 126440

GCD(872, 580) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 329

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

LCM(4, 329) = 1316

GCD(4, 329) = ( 4 x 329 ) / 1316

GCD(4, 329) = 1316 / 1316

GCD(4, 329) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 847

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

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

GCD(1, 847) = 847 / 847

GCD(1, 847) = 1

GCD of 872, 580, 329, 847 is 1
