Therefore, GCD of numbers 322, 309, 778 is 1

Given Input Data is 322, 309, 778

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

Prime Factorization of 322 is 2 x 7 x 23

Prime Factorization of 309 is 3 x 103

Prime Factorization of 778 is 2 x 389

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(322, 309) = 99498

GCD(322, 309) = ( 322 x 309 ) / 99498

GCD(322, 309) = 99498 / 99498

GCD(322, 309) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 778

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

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

GCD(1, 778) = 778 / 778

GCD(1, 778) = 1

GCD of 322, 309, 778 is 1
