Greatest Common Divisior

We found the divisors of 18, 23, 54 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 18, 23, 54 is 1.

Therefore, GCD of numbers 18, 23, 54 is 1

Given Input Data is 18, 23, 54

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 23 is 23

Prime Factorization of 54 is 2 x 3 x 3 x 3

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, 23) = 414

GCD(18, 23) = ( 18 x 23 ) / 414

GCD(18, 23) = 414 / 414

GCD(18, 23) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 54

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

LCM(1, 54) = 54

GCD(1, 54) = ( 1 x 54 ) / 54

GCD(1, 54) = 54 / 54

GCD(1, 54) = 1

GCD of 18, 23, 54 is 1
