Given Input Data is 570, 459, 642, 839

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

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 459 is 3 x 3 x 3 x 17

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 839 is 839

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(570, 459) = 87210

GCD(570, 459) = ( 570 x 459 ) / 87210

GCD(570, 459) = 261630 / 87210

GCD(570, 459) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 642

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

LCM(3, 642) = 642

GCD(3, 642) = ( 3 x 642 ) / 642

GCD(3, 642) = 1926 / 642

GCD(3, 642) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 839

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

LCM(3, 839) = 2517

GCD(3, 839) = ( 3 x 839 ) / 2517

GCD(3, 839) = 2517 / 2517

GCD(3, 839) = 1

GCD of 570, 459, 642, 839 is 1
