Given Input Data is 903, 819, 443

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

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 443 is 443

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(903, 819) = 35217

GCD(903, 819) = ( 903 x 819 ) / 35217

GCD(903, 819) = 739557 / 35217

GCD(903, 819) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 443

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

LCM(21, 443) = 9303

GCD(21, 443) = ( 21 x 443 ) / 9303

GCD(21, 443) = 9303 / 9303

GCD(21, 443) = 1

GCD of 903, 819, 443 is 1
