Greatest Common Divisior

We found the divisors of 51, 68, 24, 23 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 51, 68, 24, 23 is 1.

Therefore, GCD of numbers 51, 68, 24, 23 is 1

Given Input Data is 51, 68, 24, 23

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

Prime Factorization of 51 is 3 x 17

Prime Factorization of 68 is 2 x 2 x 17

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

Prime Factorization of 23 is 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(51, 68) = 204

GCD(51, 68) = ( 51 x 68 ) / 204

GCD(51, 68) = 3468 / 204

GCD(51, 68) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 24

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

LCM(17, 24) = 408

GCD(17, 24) = ( 17 x 24 ) / 408

GCD(17, 24) = 408 / 408

GCD(17, 24) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 23

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

LCM(1, 23) = 23

GCD(1, 23) = ( 1 x 23 ) / 23

GCD(1, 23) = 23 / 23

GCD(1, 23) = 1

GCD of 51, 68, 24, 23 is 1
