Greatest Common Divisior

We found the divisors of 44, 21, 47 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 44, 21, 47 is 1.

Therefore, GCD of numbers 44, 21, 47 is 1

Given Input Data is 44, 21, 47

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

Prime Factorization of 44 is 2 x 2 x 11

Prime Factorization of 21 is 3 x 7

Prime Factorization of 47 is 47

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(44, 21) = 924

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

GCD(44, 21) = 924 / 924

GCD(44, 21) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 47

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

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

GCD(1, 47) = 47 / 47

GCD(1, 47) = 1

GCD of 44, 21, 47 is 1
