So the Greatest Common Divisior 89, 97, 81 is 1.

Therefore, GCD of numbers 89, 97, 81 is 1

Given Input Data is 89, 97, 81

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

Prime Factorization of 89 is 89

Prime Factorization of 97 is 97

Prime Factorization of 81 is 3 x 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(89, 97) = 8633

GCD(89, 97) = ( 89 x 97 ) / 8633

GCD(89, 97) = 8633 / 8633

GCD(89, 97) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

GCD of 89, 97, 81 is 1
