Greatest Common Divisior

We found the divisors of 33, 721, 605, 441 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 33, 721, 605, 441 is 1.

Therefore, GCD of numbers 33, 721, 605, 441 is 1

Given Input Data is 33, 721, 605, 441

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

Prime Factorization of 33 is 3 x 11

Prime Factorization of 721 is 7 x 103

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 441 is 3 x 3 x 7 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(33, 721) = 23793

GCD(33, 721) = ( 33 x 721 ) / 23793

GCD(33, 721) = 23793 / 23793

GCD(33, 721) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 605

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

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

GCD(1, 605) = 605 / 605

GCD(1, 605) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 441

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

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

GCD(1, 441) = 441 / 441

GCD(1, 441) = 1

GCD of 33, 721, 605, 441 is 1
