Given Input Data is 444, 531, 286, 391

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

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

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 391 is 17 x 23

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(444, 531) = 78588

GCD(444, 531) = ( 444 x 531 ) / 78588

GCD(444, 531) = 235764 / 78588

GCD(444, 531) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 286

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

LCM(3, 286) = 858

GCD(3, 286) = ( 3 x 286 ) / 858

GCD(3, 286) = 858 / 858

GCD(3, 286) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 391

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

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

GCD(1, 391) = 391 / 391

GCD(1, 391) = 1

GCD of 444, 531, 286, 391 is 1
