Therefore, GCD of numbers 399, 493, 439, 903 is 1

Given Input Data is 399, 493, 439, 903

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

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 493 is 17 x 29

Prime Factorization of 439 is 439

Prime Factorization of 903 is 3 x 7 x 43

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(399, 493) = 196707

GCD(399, 493) = ( 399 x 493 ) / 196707

GCD(399, 493) = 196707 / 196707

GCD(399, 493) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 439

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

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

GCD(1, 439) = 439 / 439

GCD(1, 439) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 903

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

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

GCD(1, 903) = 903 / 903

GCD(1, 903) = 1

GCD of 399, 493, 439, 903 is 1
