Greatest Common Divisior

We found the divisors of 20, 339, 609, 609 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 20, 339, 609, 609 is 1.

Therefore, GCD of numbers 20, 339, 609, 609 is 1

Given Input Data is 20, 339, 609, 609

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 339 is 3 x 113

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 609 is 3 x 7 x 29

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(20, 339) = 6780

GCD(20, 339) = ( 20 x 339 ) / 6780

GCD(20, 339) = 6780 / 6780

GCD(20, 339) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 609

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

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

GCD(1, 609) = 609 / 609

GCD(1, 609) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 609

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

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

GCD(1, 609) = 609 / 609

GCD(1, 609) = 1

GCD of 20, 339, 609, 609 is 1
