Greatest Common Divisior

We found the divisors of 84, 38, 27 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 84, 38, 27 is 1.

Therefore, GCD of numbers 84, 38, 27 is 1

Given Input Data is 84, 38, 27

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 38 is 2 x 19

Prime Factorization of 27 is 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(84, 38) = 1596

GCD(84, 38) = ( 84 x 38 ) / 1596

GCD(84, 38) = 3192 / 1596

GCD(84, 38) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 27

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

LCM(2, 27) = 54

GCD(2, 27) = ( 2 x 27 ) / 54

GCD(2, 27) = 54 / 54

GCD(2, 27) = 1

GCD of 84, 38, 27 is 1
