Greatest Common Divisior

We found the divisors of 159, 609, 445, 404 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 159, 609, 445, 404 is 1.

Therefore, GCD of numbers 159, 609, 445, 404 is 1

Given Input Data is 159, 609, 445, 404

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

Prime Factorization of 159 is 3 x 53

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 445 is 5 x 89

Prime Factorization of 404 is 2 x 2 x 101

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(159, 609) = 32277

GCD(159, 609) = ( 159 x 609 ) / 32277

GCD(159, 609) = 96831 / 32277

GCD(159, 609) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 445

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

LCM(3, 445) = 1335

GCD(3, 445) = ( 3 x 445 ) / 1335

GCD(3, 445) = 1335 / 1335

GCD(3, 445) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 404

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

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

GCD(1, 404) = 404 / 404

GCD(1, 404) = 1

GCD of 159, 609, 445, 404 is 1
