So the Greatest Common Divisior 27, 81, 47 is 1.

Therefore, GCD of numbers 27, 81, 47 is 1

Given Input Data is 27, 81, 47

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 81 is 3 x 3 x 3 x 3

Prime Factorization of 47 is 47

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, 81) = 81

GCD(27, 81) = ( 27 x 81 ) / 81

GCD(27, 81) = 2187 / 81

GCD(27, 81) = 27

Step2:

Here we consider the GCD from the above i.e. 27 as first number and the next as 47

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

LCM(27, 47) = 1269

GCD(27, 47) = ( 27 x 47 ) / 1269

GCD(27, 47) = 1269 / 1269

GCD(27, 47) = 1

GCD of 27, 81, 47 is 1
