Greatest Common Divisior

We found the divisors of 27, 12, 82 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 27, 12, 82 is 1.

Therefore, GCD of numbers 27, 12, 82 is 1

Given Input Data is 27, 12, 82

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

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 82 is 2 x 41

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(27, 12) = 108

GCD(27, 12) = ( 27 x 12 ) / 108

GCD(27, 12) = 324 / 108

GCD(27, 12) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 82

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

LCM(3, 82) = 246

GCD(3, 82) = ( 3 x 82 ) / 246

GCD(3, 82) = 246 / 246

GCD(3, 82) = 1

GCD of 27, 12, 82 is 1
