So the Greatest Common Divisior 405, 227, 28 is 1.

Therefore, GCD of numbers 405, 227, 28 is 1

Given Input Data is 405, 227, 28

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

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 227 is 227

Prime Factorization of 28 is 2 x 2 x 7

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(405, 227) = 91935

GCD(405, 227) = ( 405 x 227 ) / 91935

GCD(405, 227) = 91935 / 91935

GCD(405, 227) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 28

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

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

GCD(1, 28) = 28 / 28

GCD(1, 28) = 1

GCD of 405, 227, 28 is 1
