Therefore, GCD of numbers 442, 403, 11, 819 is 1

Given Input Data is 442, 403, 11, 819

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

Prime Factorization of 442 is 2 x 13 x 17

Prime Factorization of 403 is 13 x 31

Prime Factorization of 11 is 11

Prime Factorization of 819 is 3 x 3 x 7 x 13

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(442, 403) = 13702

GCD(442, 403) = ( 442 x 403 ) / 13702

GCD(442, 403) = 178126 / 13702

GCD(442, 403) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 11

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

LCM(13, 11) = 143

GCD(13, 11) = ( 13 x 11 ) / 143

GCD(13, 11) = 143 / 143

GCD(13, 11) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 819

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

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

GCD(1, 819) = 819 / 819

GCD(1, 819) = 1

GCD of 442, 403, 11, 819 is 1
