Given Input Data is 447, 408, 287

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

Prime Factorization of 447 is 3 x 149

Prime Factorization of 408 is 2 x 2 x 2 x 3 x 17

Prime Factorization of 287 is 7 x 41

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(447, 408) = 60792

GCD(447, 408) = ( 447 x 408 ) / 60792

GCD(447, 408) = 182376 / 60792

GCD(447, 408) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 287

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

LCM(3, 287) = 861

GCD(3, 287) = ( 3 x 287 ) / 861

GCD(3, 287) = 861 / 861

GCD(3, 287) = 1

GCD of 447, 408, 287 is 1
