Greatest Common Divisior

We found the divisors of 11, 19, 27, 15 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 11, 19, 27, 15 is 1.

Therefore, GCD of numbers 11, 19, 27, 15 is 1

Given Input Data is 11, 19, 27, 15

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

Prime Factorization of 11 is 11

Prime Factorization of 19 is 19

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 15 is 3 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(11, 19) = 209

GCD(11, 19) = ( 11 x 19 ) / 209

GCD(11, 19) = 209 / 209

GCD(11, 19) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 27

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

LCM(1, 27) = 27

GCD(1, 27) = ( 1 x 27 ) / 27

GCD(1, 27) = 27 / 27

GCD(1, 27) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

GCD of 11, 19, 27, 15 is 1
