Greatest Common Divisior

We found the divisors of 15, 11, 99 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 15, 11, 99 is 1.

Therefore, GCD of numbers 15, 11, 99 is 1

Given Input Data is 15, 11, 99

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 11 is 11

Prime Factorization of 99 is 3 x 3 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(15, 11) = 165

GCD(15, 11) = ( 15 x 11 ) / 165

GCD(15, 11) = 165 / 165

GCD(15, 11) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 99

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

LCM(1, 99) = 99

GCD(1, 99) = ( 1 x 99 ) / 99

GCD(1, 99) = 99 / 99

GCD(1, 99) = 1

GCD of 15, 11, 99 is 1
