Given Input Data is 255, 669, 191

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

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 669 is 3 x 223

Prime Factorization of 191 is 191

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(255, 669) = 56865

GCD(255, 669) = ( 255 x 669 ) / 56865

GCD(255, 669) = 170595 / 56865

GCD(255, 669) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 191

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

LCM(3, 191) = 573

GCD(3, 191) = ( 3 x 191 ) / 573

GCD(3, 191) = 573 / 573

GCD(3, 191) = 1

GCD of 255, 669, 191 is 1
