Greatest Common Divisior

We found the divisors of 22, 15, 51 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 22, 15, 51 is 1.

Therefore, GCD of numbers 22, 15, 51 is 1

Given Input Data is 22, 15, 51

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

Prime Factorization of 22 is 2 x 11

Prime Factorization of 15 is 3 x 5

Prime Factorization of 51 is 3 x 17

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(22, 15) = 330

GCD(22, 15) = ( 22 x 15 ) / 330

GCD(22, 15) = 330 / 330

GCD(22, 15) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 51

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

LCM(1, 51) = 51

GCD(1, 51) = ( 1 x 51 ) / 51

GCD(1, 51) = 51 / 51

GCD(1, 51) = 1

GCD of 22, 15, 51 is 1
