Given Input Data is 873, 891, 321, 703

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

Prime Factorization of 873 is 3 x 3 x 97

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

Prime Factorization of 321 is 3 x 107

Prime Factorization of 703 is 19 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(873, 891) = 86427

GCD(873, 891) = ( 873 x 891 ) / 86427

GCD(873, 891) = 777843 / 86427

GCD(873, 891) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 321

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

LCM(9, 321) = 963

GCD(9, 321) = ( 9 x 321 ) / 963

GCD(9, 321) = 2889 / 963

GCD(9, 321) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 703

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

LCM(3, 703) = 2109

GCD(3, 703) = ( 3 x 703 ) / 2109

GCD(3, 703) = 2109 / 2109

GCD(3, 703) = 1

GCD of 873, 891, 321, 703 is 1
