Therefore, GCD of numbers 861, 723, 227, 401 is 1

Given Input Data is 861, 723, 227, 401

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 723 is 3 x 241

Prime Factorization of 227 is 227

Prime Factorization of 401 is 401

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(861, 723) = 207501

GCD(861, 723) = ( 861 x 723 ) / 207501

GCD(861, 723) = 622503 / 207501

GCD(861, 723) = 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 401

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

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

GCD(1, 401) = 401 / 401

GCD(1, 401) = 1

GCD of 861, 723, 227, 401 is 1
