Therefore, GCD of numbers 847, 819, 30, 311 is 1

Given Input Data is 847, 819, 30, 311

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

Prime Factorization of 847 is 7 x 11 x 11

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 311 is 311

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(847, 819) = 99099

GCD(847, 819) = ( 847 x 819 ) / 99099

GCD(847, 819) = 693693 / 99099

GCD(847, 819) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 30

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

LCM(7, 30) = 210

GCD(7, 30) = ( 7 x 30 ) / 210

GCD(7, 30) = 210 / 210

GCD(7, 30) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 311

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

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

GCD(1, 311) = 311 / 311

GCD(1, 311) = 1

GCD of 847, 819, 30, 311 is 1
