Therefore, GCD of numbers 680, 710, 19 is 1

Given Input Data is 680, 710, 19

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

Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17

Prime Factorization of 710 is 2 x 5 x 71

Prime Factorization of 19 is 19

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(680, 710) = 48280

GCD(680, 710) = ( 680 x 710 ) / 48280

GCD(680, 710) = 482800 / 48280

GCD(680, 710) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 19

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

LCM(10, 19) = 190

GCD(10, 19) = ( 10 x 19 ) / 190

GCD(10, 19) = 190 / 190

GCD(10, 19) = 1

GCD of 680, 710, 19 is 1
