Therefore, GCD of numbers 817, 418, 834, 509 is 1

Given Input Data is 817, 418, 834, 509

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

Prime Factorization of 817 is 19 x 43

Prime Factorization of 418 is 2 x 11 x 19

Prime Factorization of 834 is 2 x 3 x 139

Prime Factorization of 509 is 509

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(817, 418) = 17974

GCD(817, 418) = ( 817 x 418 ) / 17974

GCD(817, 418) = 341506 / 17974

GCD(817, 418) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 834

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

LCM(19, 834) = 15846

GCD(19, 834) = ( 19 x 834 ) / 15846

GCD(19, 834) = 15846 / 15846

GCD(19, 834) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 509

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

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

GCD(1, 509) = 509 / 509

GCD(1, 509) = 1

GCD of 817, 418, 834, 509 is 1
