Therefore, GCD of numbers 430, 285, 239 is 1

Given Input Data is 430, 285, 239

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

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 239 is 239

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(430, 285) = 24510

GCD(430, 285) = ( 430 x 285 ) / 24510

GCD(430, 285) = 122550 / 24510

GCD(430, 285) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 239

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

LCM(5, 239) = 1195

GCD(5, 239) = ( 5 x 239 ) / 1195

GCD(5, 239) = 1195 / 1195

GCD(5, 239) = 1

GCD of 430, 285, 239 is 1
