Therefore, GCD of numbers 820, 835, 859 is 1

Given Input Data is 820, 835, 859

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

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 835 is 5 x 167

Prime Factorization of 859 is 859

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(820, 835) = 136940

GCD(820, 835) = ( 820 x 835 ) / 136940

GCD(820, 835) = 684700 / 136940

GCD(820, 835) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 859

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

LCM(5, 859) = 4295

GCD(5, 859) = ( 5 x 859 ) / 4295

GCD(5, 859) = 4295 / 4295

GCD(5, 859) = 1

GCD of 820, 835, 859 is 1
