Greatest Common Divisior

We found the divisors of 16, 18, 73 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 16, 18, 73 is 1.

Therefore, GCD of numbers 16, 18, 73 is 1

Given Input Data is 16, 18, 73

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

Prime Factorization of 16 is 2 x 2 x 2 x 2

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 73 is 73

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(16, 18) = 144

GCD(16, 18) = ( 16 x 18 ) / 144

GCD(16, 18) = 288 / 144

GCD(16, 18) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 73

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

LCM(2, 73) = 146

GCD(2, 73) = ( 2 x 73 ) / 146

GCD(2, 73) = 146 / 146

GCD(2, 73) = 1

GCD of 16, 18, 73 is 1
