Given Input Data is 639, 204, 277

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

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 204 is 2 x 2 x 3 x 17

Prime Factorization of 277 is 277

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(639, 204) = 43452

GCD(639, 204) = ( 639 x 204 ) / 43452

GCD(639, 204) = 130356 / 43452

GCD(639, 204) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 277

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

LCM(3, 277) = 831

GCD(3, 277) = ( 3 x 277 ) / 831

GCD(3, 277) = 831 / 831

GCD(3, 277) = 1

GCD of 639, 204, 277 is 1
