Given Input Data is 426, 939, 772

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

Prime Factorization of 426 is 2 x 3 x 71

Prime Factorization of 939 is 3 x 313

Prime Factorization of 772 is 2 x 2 x 193

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(426, 939) = 133338

GCD(426, 939) = ( 426 x 939 ) / 133338

GCD(426, 939) = 400014 / 133338

GCD(426, 939) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 772

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

LCM(3, 772) = 2316

GCD(3, 772) = ( 3 x 772 ) / 2316

GCD(3, 772) = 2316 / 2316

GCD(3, 772) = 1

GCD of 426, 939, 772 is 1
