Given Input Data is 891, 450, 259

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

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 259 is 7 x 37

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(891, 450) = 44550

GCD(891, 450) = ( 891 x 450 ) / 44550

GCD(891, 450) = 400950 / 44550

GCD(891, 450) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 259

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

LCM(9, 259) = 2331

GCD(9, 259) = ( 9 x 259 ) / 2331

GCD(9, 259) = 2331 / 2331

GCD(9, 259) = 1

GCD of 891, 450, 259 is 1
