1, 89

Greatest Common Divisior

We found the divisors of 12, 13, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 12, 13, 89 is 1.

Therefore, GCD of numbers 12, 13, 89 is 1

Given Input Data is 12, 13, 89

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

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 13 is 13

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(12, 13) = 156

GCD(12, 13) = ( 12 x 13 ) / 156

GCD(12, 13) = 156 / 156

GCD(12, 13) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 89

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

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

GCD(1, 89) = 89 / 89

GCD(1, 89) = 1

GCD of 12, 13, 89 is 1
