Therefore, GCD of numbers 305, 861, 230 is 1

Given Input Data is 305, 861, 230

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

Prime Factorization of 305 is 5 x 61

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 230 is 2 x 5 x 23

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(305, 861) = 262605

GCD(305, 861) = ( 305 x 861 ) / 262605

GCD(305, 861) = 262605 / 262605

GCD(305, 861) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 230

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

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

GCD(1, 230) = 230 / 230

GCD(1, 230) = 1

GCD of 305, 861, 230 is 1
