Given Input Data is 321, 822, 836

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

Prime Factorization of 321 is 3 x 107

Prime Factorization of 822 is 2 x 3 x 137

Prime Factorization of 836 is 2 x 2 x 11 x 19

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(321, 822) = 87954

GCD(321, 822) = ( 321 x 822 ) / 87954

GCD(321, 822) = 263862 / 87954

GCD(321, 822) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 836

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

LCM(3, 836) = 2508

GCD(3, 836) = ( 3 x 836 ) / 2508

GCD(3, 836) = 2508 / 2508

GCD(3, 836) = 1

GCD of 321, 822, 836 is 1
