Given Input Data is 515, 435, 819

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

Prime Factorization of 515 is 5 x 103

Prime Factorization of 435 is 3 x 5 x 29

Prime Factorization of 819 is 3 x 3 x 7 x 13

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(515, 435) = 44805

GCD(515, 435) = ( 515 x 435 ) / 44805

GCD(515, 435) = 224025 / 44805

GCD(515, 435) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 819

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

LCM(5, 819) = 4095

GCD(5, 819) = ( 5 x 819 ) / 4095

GCD(5, 819) = 4095 / 4095

GCD(5, 819) = 1

GCD of 515, 435, 819 is 1
