Therefore, GCD of numbers 809, 225, 430 is 1

Given Input Data is 809, 225, 430

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

Prime Factorization of 809 is 809

Prime Factorization of 225 is 3 x 3 x 5 x 5

Prime Factorization of 430 is 2 x 5 x 43

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(809, 225) = 182025

GCD(809, 225) = ( 809 x 225 ) / 182025

GCD(809, 225) = 182025 / 182025

GCD(809, 225) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 430

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

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

GCD(1, 430) = 430 / 430

GCD(1, 430) = 1

GCD of 809, 225, 430 is 1
