Therefore, GCD of numbers 730, 391, 626 is 1

Given Input Data is 730, 391, 626

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 391 is 17 x 23

Prime Factorization of 626 is 2 x 313

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, 391) = 285430

GCD(730, 391) = ( 730 x 391 ) / 285430

GCD(730, 391) = 285430 / 285430

GCD(730, 391) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 626

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

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

GCD(1, 626) = 626 / 626

GCD(1, 626) = 1

GCD of 730, 391, 626 is 1
