Greatest Common Divisior

We found the divisors of 81, 17, 93 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 81, 17, 93 is 1.

Therefore, GCD of numbers 81, 17, 93 is 1

Given Input Data is 81, 17, 93

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

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 17 is 17

Prime Factorization of 93 is 3 x 31

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(81, 17) = 1377

GCD(81, 17) = ( 81 x 17 ) / 1377

GCD(81, 17) = 1377 / 1377

GCD(81, 17) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 93

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

LCM(1, 93) = 93

GCD(1, 93) = ( 1 x 93 ) / 93

GCD(1, 93) = 93 / 93

GCD(1, 93) = 1

GCD of 81, 17, 93 is 1
