We found the divisors of 404, 111, 75, 638 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 404, 111, 75, 638 is 1.

Therefore, GCD of numbers 404, 111, 75, 638 is 1

Given Input Data is 404, 111, 75, 638

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

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 111 is 3 x 37

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 638 is 2 x 11 x 29

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(404, 111) = 44844

GCD(404, 111) = ( 404 x 111 ) / 44844

GCD(404, 111) = 44844 / 44844

GCD(404, 111) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 75

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

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

GCD(1, 75) = 75 / 75

GCD(1, 75) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 638

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

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

GCD(1, 638) = 638 / 638

GCD(1, 638) = 1

GCD of 404, 111, 75, 638 is 1
