Greatest Common Divisior

We found the divisors of 630, 401, 321, 231 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 630, 401, 321, 231 is 1.

Therefore, GCD of numbers 630, 401, 321, 231 is 1

Given Input Data is 630, 401, 321, 231

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

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 401 is 401

Prime Factorization of 321 is 3 x 107

Prime Factorization of 231 is 3 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(630, 401) = 252630

GCD(630, 401) = ( 630 x 401 ) / 252630

GCD(630, 401) = 252630 / 252630

GCD(630, 401) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 321

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

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

GCD(1, 321) = 321 / 321

GCD(1, 321) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 231

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

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

GCD(1, 231) = 231 / 231

GCD(1, 231) = 1

GCD of 630, 401, 321, 231 is 1
