Given Input Data is 211, 645, 911

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

Prime Factorization of 211 is 211

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 911 is 911

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(211, 645) = 136095

GCD(211, 645) = ( 211 x 645 ) / 136095

GCD(211, 645) = 136095 / 136095

GCD(211, 645) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 911

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

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

GCD(1, 911) = 911 / 911

GCD(1, 911) = 1

GCD of 211, 645, 911 is 1
