Therefore, GCD of numbers 321, 303, 467, 640 is 1

Given Input Data is 321, 303, 467, 640

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

Prime Factorization of 321 is 3 x 107

Prime Factorization of 303 is 3 x 101

Prime Factorization of 467 is 467

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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(321, 303) = 32421

GCD(321, 303) = ( 321 x 303 ) / 32421

GCD(321, 303) = 97263 / 32421

GCD(321, 303) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 467

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

LCM(3, 467) = 1401

GCD(3, 467) = ( 3 x 467 ) / 1401

GCD(3, 467) = 1401 / 1401

GCD(3, 467) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 640

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

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

GCD(1, 640) = 640 / 640

GCD(1, 640) = 1

GCD of 321, 303, 467, 640 is 1
