Greatest Common Divisior

We found the divisors of 400, 401, 622, 623 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 400, 401, 622, 623 is 1.

Therefore, GCD of numbers 400, 401, 622, 623 is 1

Given Input Data is 400, 401, 622, 623

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

Prime Factorization of 400 is 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 401 is 401

Prime Factorization of 622 is 2 x 311

Prime Factorization of 623 is 7 x 89

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(400, 401) = 160400

GCD(400, 401) = ( 400 x 401 ) / 160400

GCD(400, 401) = 160400 / 160400

GCD(400, 401) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 622

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

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

GCD(1, 622) = 622 / 622

GCD(1, 622) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 623

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

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

GCD(1, 623) = 623 / 623

GCD(1, 623) = 1

GCD of 400, 401, 622, 623 is 1
