Given Input Data is 145, 475, 129

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

Prime Factorization of 145 is 5 x 29

Prime Factorization of 475 is 5 x 5 x 19

Prime Factorization of 129 is 3 x 43

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(145, 475) = 13775

GCD(145, 475) = ( 145 x 475 ) / 13775

GCD(145, 475) = 68875 / 13775

GCD(145, 475) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 129

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

LCM(5, 129) = 645

GCD(5, 129) = ( 5 x 129 ) / 645

GCD(5, 129) = 645 / 645

GCD(5, 129) = 1

GCD of 145, 475, 129 is 1
