Therefore, GCD of numbers 687, 435, 227, 323 is 1

Given Input Data is 687, 435, 227, 323

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

Prime Factorization of 687 is 3 x 229

Prime Factorization of 435 is 3 x 5 x 29

Prime Factorization of 227 is 227

Prime Factorization of 323 is 17 x 19

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(687, 435) = 99615

GCD(687, 435) = ( 687 x 435 ) / 99615

GCD(687, 435) = 298845 / 99615

GCD(687, 435) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 227

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

LCM(3, 227) = 681

GCD(3, 227) = ( 3 x 227 ) / 681

GCD(3, 227) = 681 / 681

GCD(3, 227) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 323

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

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

GCD(1, 323) = 323 / 323

GCD(1, 323) = 1

GCD of 687, 435, 227, 323 is 1
