Greatest Common Divisior

We found the divisors of 96, 81, 68, 71 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 96, 81, 68, 71 is 1.

Therefore, GCD of numbers 96, 81, 68, 71 is 1

Given Input Data is 96, 81, 68, 71

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

Prime Factorization of 96 is 2 x 2 x 2 x 2 x 2 x 3

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

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 71 is 71

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(96, 81) = 2592

GCD(96, 81) = ( 96 x 81 ) / 2592

GCD(96, 81) = 7776 / 2592

GCD(96, 81) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 68

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

LCM(3, 68) = 204

GCD(3, 68) = ( 3 x 68 ) / 204

GCD(3, 68) = 204 / 204

GCD(3, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 71

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

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

GCD(1, 71) = 71 / 71

GCD(1, 71) = 1

GCD of 96, 81, 68, 71 is 1
