Therefore, GCD of numbers 721, 510, 394 is 1

Given Input Data is 721, 510, 394

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 510 is 2 x 3 x 5 x 17

Prime Factorization of 394 is 2 x 197

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(721, 510) = 367710

GCD(721, 510) = ( 721 x 510 ) / 367710

GCD(721, 510) = 367710 / 367710

GCD(721, 510) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 394

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

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

GCD(1, 394) = 394 / 394

GCD(1, 394) = 1

GCD of 721, 510, 394 is 1
