Therefore, GCD of numbers 555, 410, 12, 809 is 1

Given Input Data is 555, 410, 12, 809

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

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 410 is 2 x 5 x 41

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 809 is 809

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(555, 410) = 45510

GCD(555, 410) = ( 555 x 410 ) / 45510

GCD(555, 410) = 227550 / 45510

GCD(555, 410) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 12

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

LCM(5, 12) = 60

GCD(5, 12) = ( 5 x 12 ) / 60

GCD(5, 12) = 60 / 60

GCD(5, 12) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 809

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

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

GCD(1, 809) = 809 / 809

GCD(1, 809) = 1

GCD of 555, 410, 12, 809 is 1
