We found the divisors of 775, 866, 422, 231 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 775, 866, 422, 231 is 1.

Therefore, GCD of numbers 775, 866, 422, 231 is 1

Given Input Data is 775, 866, 422, 231

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

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 866 is 2 x 433

Prime Factorization of 422 is 2 x 211

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(775, 866) = 671150

GCD(775, 866) = ( 775 x 866 ) / 671150

GCD(775, 866) = 671150 / 671150

GCD(775, 866) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 422

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

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

GCD(1, 422) = 422 / 422

GCD(1, 422) = 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 775, 866, 422, 231 is 1
