Therefore, GCD of numbers 380, 817, 612 is 1

Given Input Data is 380, 817, 612

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

Prime Factorization of 380 is 2 x 2 x 5 x 19

Prime Factorization of 817 is 19 x 43

Prime Factorization of 612 is 2 x 2 x 3 x 3 x 17

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(380, 817) = 16340

GCD(380, 817) = ( 380 x 817 ) / 16340

GCD(380, 817) = 310460 / 16340

GCD(380, 817) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 612

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

LCM(19, 612) = 11628

GCD(19, 612) = ( 19 x 612 ) / 11628

GCD(19, 612) = 11628 / 11628

GCD(19, 612) = 1

GCD of 380, 817, 612 is 1
