Given Input Data is 873, 861, 518, 385

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

Prime Factorization of 873 is 3 x 3 x 97

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 518 is 2 x 7 x 37

Prime Factorization of 385 is 5 x 7 x 11

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(873, 861) = 250551

GCD(873, 861) = ( 873 x 861 ) / 250551

GCD(873, 861) = 751653 / 250551

GCD(873, 861) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 518

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

LCM(3, 518) = 1554

GCD(3, 518) = ( 3 x 518 ) / 1554

GCD(3, 518) = 1554 / 1554

GCD(3, 518) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 385

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

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

GCD(1, 385) = 385 / 385

GCD(1, 385) = 1

GCD of 873, 861, 518, 385 is 1
