Given Input Data is 609, 495, 859, 285

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

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 495 is 3 x 3 x 5 x 11

Prime Factorization of 859 is 859

Prime Factorization of 285 is 3 x 5 x 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(609, 495) = 100485

GCD(609, 495) = ( 609 x 495 ) / 100485

GCD(609, 495) = 301455 / 100485

GCD(609, 495) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 859

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

LCM(3, 859) = 2577

GCD(3, 859) = ( 3 x 859 ) / 2577

GCD(3, 859) = 2577 / 2577

GCD(3, 859) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 285

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

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

GCD(1, 285) = 285 / 285

GCD(1, 285) = 1

GCD of 609, 495, 859, 285 is 1
