Given Input Data is 180, 764, 487

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

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

Prime Factorization of 764 is 2 x 2 x 191

Prime Factorization of 487 is 487

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(180, 764) = 34380

GCD(180, 764) = ( 180 x 764 ) / 34380

GCD(180, 764) = 137520 / 34380

GCD(180, 764) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 487

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

LCM(4, 487) = 1948

GCD(4, 487) = ( 4 x 487 ) / 1948

GCD(4, 487) = 1948 / 1948

GCD(4, 487) = 1

GCD of 180, 764, 487 is 1
