Therefore, GCD of numbers 730, 428, 711 is 1

Given Input Data is 730, 428, 711

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

Prime Factorization of 730 is 2 x 5 x 73

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 711 is 3 x 3 x 79

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(730, 428) = 156220

GCD(730, 428) = ( 730 x 428 ) / 156220

GCD(730, 428) = 312440 / 156220

GCD(730, 428) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 711

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

LCM(2, 711) = 1422

GCD(2, 711) = ( 2 x 711 ) / 1422

GCD(2, 711) = 1422 / 1422

GCD(2, 711) = 1

GCD of 730, 428, 711 is 1
