Greatest Common Divisior

We found the divisors of 24, 12, 13 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 24, 12, 13 is 1.

Therefore, GCD of numbers 24, 12, 13 is 1

Given Input Data is 24, 12, 13

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

Prime Factorization of 24 is 2 x 2 x 2 x 3

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 13 is 13

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(24, 12) = 24

GCD(24, 12) = ( 24 x 12 ) / 24

GCD(24, 12) = 288 / 24

GCD(24, 12) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 13

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

GCD of 24, 12, 13 is 1
