Given Input Data is 663, 676, 569, 173

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 676 is 2 x 2 x 13 x 13

Prime Factorization of 569 is 569

Prime Factorization of 173 is 173

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(663, 676) = 34476

GCD(663, 676) = ( 663 x 676 ) / 34476

GCD(663, 676) = 448188 / 34476

GCD(663, 676) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 569

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

LCM(13, 569) = 7397

GCD(13, 569) = ( 13 x 569 ) / 7397

GCD(13, 569) = 7397 / 7397

GCD(13, 569) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 173

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

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

GCD(1, 173) = 173 / 173

GCD(1, 173) = 1

GCD of 663, 676, 569, 173 is 1
