Given Input Data is 687, 558, 439

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

Prime Factorization of 687 is 3 x 229

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 439 is 439

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(687, 558) = 127782

GCD(687, 558) = ( 687 x 558 ) / 127782

GCD(687, 558) = 383346 / 127782

GCD(687, 558) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 439

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

LCM(3, 439) = 1317

GCD(3, 439) = ( 3 x 439 ) / 1317

GCD(3, 439) = 1317 / 1317

GCD(3, 439) = 1

GCD of 687, 558, 439 is 1
