Given Input Data is 144, 388, 479

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

Prime Factorization of 144 is 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 388 is 2 x 2 x 97

Prime Factorization of 479 is 479

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(144, 388) = 13968

GCD(144, 388) = ( 144 x 388 ) / 13968

GCD(144, 388) = 55872 / 13968

GCD(144, 388) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 479

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

LCM(4, 479) = 1916

GCD(4, 479) = ( 4 x 479 ) / 1916

GCD(4, 479) = 1916 / 1916

GCD(4, 479) = 1

GCD of 144, 388, 479 is 1
