Given Input Data is 785, 645, 454

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

Prime Factorization of 785 is 5 x 157

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 454 is 2 x 227

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(785, 645) = 101265

GCD(785, 645) = ( 785 x 645 ) / 101265

GCD(785, 645) = 506325 / 101265

GCD(785, 645) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 454

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

LCM(5, 454) = 2270

GCD(5, 454) = ( 5 x 454 ) / 2270

GCD(5, 454) = 2270 / 2270

GCD(5, 454) = 1

GCD of 785, 645, 454 is 1
