Given Input Data is 663, 372, 115

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 372 is 2 x 2 x 3 x 31

Prime Factorization of 115 is 5 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(663, 372) = 82212

GCD(663, 372) = ( 663 x 372 ) / 82212

GCD(663, 372) = 246636 / 82212

GCD(663, 372) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 115

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

LCM(3, 115) = 345

GCD(3, 115) = ( 3 x 115 ) / 345

GCD(3, 115) = 345 / 345

GCD(3, 115) = 1

GCD of 663, 372, 115 is 1
