Therefore, GCD of numbers 195, 768, 570, 449 is 1

Given Input Data is 195, 768, 570, 449

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

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 768 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 449 is 449

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(195, 768) = 49920

GCD(195, 768) = ( 195 x 768 ) / 49920

GCD(195, 768) = 149760 / 49920

GCD(195, 768) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 570

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

LCM(3, 570) = 570

GCD(3, 570) = ( 3 x 570 ) / 570

GCD(3, 570) = 1710 / 570

GCD(3, 570) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 449

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

LCM(3, 449) = 1347

GCD(3, 449) = ( 3 x 449 ) / 1347

GCD(3, 449) = 1347 / 1347

GCD(3, 449) = 1

GCD of 195, 768, 570, 449 is 1
