Given Input Data is 381, 597, 63, 191

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

Prime Factorization of 381 is 3 x 127

Prime Factorization of 597 is 3 x 199

Prime Factorization of 63 is 3 x 3 x 7

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(381, 597) = 75819

GCD(381, 597) = ( 381 x 597 ) / 75819

GCD(381, 597) = 227457 / 75819

GCD(381, 597) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 63

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

LCM(3, 63) = 63

GCD(3, 63) = ( 3 x 63 ) / 63

GCD(3, 63) = 189 / 63

GCD(3, 63) = 3

Step3:

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 381, 597, 63, 191 is 1
