Given Input Data is 432, 558, 161

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

Prime Factorization of 432 is 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 161 is 7 x 23

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(432, 558) = 13392

GCD(432, 558) = ( 432 x 558 ) / 13392

GCD(432, 558) = 241056 / 13392

GCD(432, 558) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 161

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

LCM(18, 161) = 2898

GCD(18, 161) = ( 18 x 161 ) / 2898

GCD(18, 161) = 2898 / 2898

GCD(18, 161) = 1

GCD of 432, 558, 161 is 1
