Greatest Common Divisior

We found the divisors of 18, 33, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 18, 33, 89 is 1.

Therefore, GCD of numbers 18, 33, 89 is 1

Given Input Data is 18, 33, 89

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 33 is 3 x 11

Prime Factorization of 89 is 89

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(18, 33) = 198

GCD(18, 33) = ( 18 x 33 ) / 198

GCD(18, 33) = 594 / 198

GCD(18, 33) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 89

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

LCM(3, 89) = 267

GCD(3, 89) = ( 3 x 89 ) / 267

GCD(3, 89) = 267 / 267

GCD(3, 89) = 1

GCD of 18, 33, 89 is 1
