Greatest Common Divisior

We found the divisors of 24, 4, 81, 40 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 24, 4, 81, 40 is 1.

Therefore, GCD of numbers 24, 4, 81, 40 is 1

Given Input Data is 24, 4, 81, 40

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

Prime Factorization of 24 is 2 x 2 x 2 x 3

Prime Factorization of 4 is 2 x 2

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

Prime Factorization of 40 is 2 x 2 x 2 x 5

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(24, 4) = 24

GCD(24, 4) = ( 24 x 4 ) / 24

GCD(24, 4) = 96 / 24

GCD(24, 4) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 81

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

LCM(4, 81) = 324

GCD(4, 81) = ( 4 x 81 ) / 324

GCD(4, 81) = 324 / 324

GCD(4, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 40

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

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

GCD(1, 40) = 40 / 40

GCD(1, 40) = 1

GCD of 24, 4, 81, 40 is 1
