Given Input Data is 646, 444, 286, 587

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 444 is 2 x 2 x 3 x 37

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 587 is 587

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(646, 444) = 143412

GCD(646, 444) = ( 646 x 444 ) / 143412

GCD(646, 444) = 286824 / 143412

GCD(646, 444) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 286

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

LCM(2, 286) = 286

GCD(2, 286) = ( 2 x 286 ) / 286

GCD(2, 286) = 572 / 286

GCD(2, 286) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 587

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

LCM(2, 587) = 1174

GCD(2, 587) = ( 2 x 587 ) / 1174

GCD(2, 587) = 1174 / 1174

GCD(2, 587) = 1

GCD of 646, 444, 286, 587 is 1
