Greatest Common Divisior

We found the divisors of 21, 44, 14 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 21, 44, 14 is 1.

Therefore, GCD of numbers 21, 44, 14 is 1

Given Input Data is 21, 44, 14

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

Prime Factorization of 21 is 3 x 7

Prime Factorization of 44 is 2 x 2 x 11

Prime Factorization of 14 is 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(21, 44) = 924

GCD(21, 44) = ( 21 x 44 ) / 924

GCD(21, 44) = 924 / 924

GCD(21, 44) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 14

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

LCM(1, 14) = 14

GCD(1, 14) = ( 1 x 14 ) / 14

GCD(1, 14) = 14 / 14

GCD(1, 14) = 1

GCD of 21, 44, 14 is 1
