So the Greatest Common Divisior 27, 39, 17 is 1.

Therefore, GCD of numbers 27, 39, 17 is 1

Given Input Data is 27, 39, 17

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 39 is 3 x 13

Prime Factorization of 17 is 17

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, 39) = 351

GCD(27, 39) = ( 27 x 39 ) / 351

GCD(27, 39) = 1053 / 351

GCD(27, 39) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 17

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

LCM(3, 17) = 51

GCD(3, 17) = ( 3 x 17 ) / 51

GCD(3, 17) = 51 / 51

GCD(3, 17) = 1

GCD of 27, 39, 17 is 1
