We found the divisors of 321, 123, 28, 522 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 321, 123, 28, 522 is 1.

Therefore, GCD of numbers 321, 123, 28, 522 is 1

Given Input Data is 321, 123, 28, 522

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

Prime Factorization of 321 is 3 x 107

Prime Factorization of 123 is 3 x 41

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 522 is 2 x 3 x 3 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(321, 123) = 13161

GCD(321, 123) = ( 321 x 123 ) / 13161

GCD(321, 123) = 39483 / 13161

GCD(321, 123) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 28

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

LCM(3, 28) = 84

GCD(3, 28) = ( 3 x 28 ) / 84

GCD(3, 28) = 84 / 84

GCD(3, 28) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 522

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

LCM(1, 522) = 522

GCD(1, 522) = ( 1 x 522 ) / 522

GCD(1, 522) = 522 / 522

GCD(1, 522) = 1

GCD of 321, 123, 28, 522 is 1
