Given Input Data is 666, 198, 191, 636

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

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 198 is 2 x 3 x 3 x 11

Prime Factorization of 191 is 191

Prime Factorization of 636 is 2 x 2 x 3 x 53

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(666, 198) = 7326

GCD(666, 198) = ( 666 x 198 ) / 7326

GCD(666, 198) = 131868 / 7326

GCD(666, 198) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 191

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

LCM(18, 191) = 3438

GCD(18, 191) = ( 18 x 191 ) / 3438

GCD(18, 191) = 3438 / 3438

GCD(18, 191) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 636

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

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

GCD(1, 636) = 636 / 636

GCD(1, 636) = 1

GCD of 666, 198, 191, 636 is 1
