Greatest Common Divisior

We found the divisors of 28, 11, 22 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 28, 11, 22 is 1.

Therefore, GCD of numbers 28, 11, 22 is 1

Given Input Data is 28, 11, 22

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 11 is 11

Prime Factorization of 22 is 2 x 11

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(28, 11) = 308

GCD(28, 11) = ( 28 x 11 ) / 308

GCD(28, 11) = 308 / 308

GCD(28, 11) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 22

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

LCM(1, 22) = 22

GCD(1, 22) = ( 1 x 22 ) / 22

GCD(1, 22) = 22 / 22

GCD(1, 22) = 1

GCD of 28, 11, 22 is 1
