Therefore, GCD of numbers 408, 332, 81 is 1

Given Input Data is 408, 332, 81

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

Prime Factorization of 408 is 2 x 2 x 2 x 3 x 17

Prime Factorization of 332 is 2 x 2 x 83

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(408, 332) = 33864

GCD(408, 332) = ( 408 x 332 ) / 33864

GCD(408, 332) = 135456 / 33864

GCD(408, 332) = 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

GCD of 408, 332, 81 is 1
