Greatest Common Divisior

We found the divisors of 96, 5, 21, 68 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 96, 5, 21, 68 is 1.

Therefore, GCD of numbers 96, 5, 21, 68 is 1

Given Input Data is 96, 5, 21, 68

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 5 is 5

Prime Factorization of 21 is 3 x 7

Prime Factorization of 68 is 2 x 2 x 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(96, 5) = 480

GCD(96, 5) = ( 96 x 5 ) / 480

GCD(96, 5) = 480 / 480

GCD(96, 5) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 68

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

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

GCD(1, 68) = 68 / 68

GCD(1, 68) = 1

GCD of 96, 5, 21, 68 is 1
