Greatest Common Divisior

We found the divisors of 44, 9, 20, 19 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 44, 9, 20, 19 is 1.

Therefore, GCD of numbers 44, 9, 20, 19 is 1

Given Input Data is 44, 9, 20, 19

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 9 is 3 x 3

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 19 is 19

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, 9) = 396

GCD(44, 9) = ( 44 x 9 ) / 396

GCD(44, 9) = 396 / 396

GCD(44, 9) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 19

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

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

GCD(1, 19) = 19 / 19

GCD(1, 19) = 1

GCD of 44, 9, 20, 19 is 1
