Therefore, GCD of numbers 129, 165, 197 is 1

Given Input Data is 129, 165, 197

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 165 is 3 x 5 x 11

Prime Factorization of 197 is 197

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, 165) = 7095

GCD(129, 165) = ( 129 x 165 ) / 7095

GCD(129, 165) = 21285 / 7095

GCD(129, 165) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 197

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

LCM(3, 197) = 591

GCD(3, 197) = ( 3 x 197 ) / 591

GCD(3, 197) = 591 / 591

GCD(3, 197) = 1

GCD of 129, 165, 197 is 1
