Given Input Data is 399, 798, 715, 284

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

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 798 is 2 x 3 x 7 x 19

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 284 is 2 x 2 x 71

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(399, 798) = 798

GCD(399, 798) = ( 399 x 798 ) / 798

GCD(399, 798) = 318402 / 798

GCD(399, 798) = 399

Step2:

Here we consider the GCD from the above i.e. 399 as first number and the next as 715

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

LCM(399, 715) = 285285

GCD(399, 715) = ( 399 x 715 ) / 285285

GCD(399, 715) = 285285 / 285285

GCD(399, 715) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 284

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

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

GCD(1, 284) = 284 / 284

GCD(1, 284) = 1

GCD of 399, 798, 715, 284 is 1
