Given Input Data is 393, 903, 451, 459

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

Prime Factorization of 393 is 3 x 131

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 451 is 11 x 41

Prime Factorization of 459 is 3 x 3 x 3 x 17

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(393, 903) = 118293

GCD(393, 903) = ( 393 x 903 ) / 118293

GCD(393, 903) = 354879 / 118293

GCD(393, 903) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 451

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

LCM(3, 451) = 1353

GCD(3, 451) = ( 3 x 451 ) / 1353

GCD(3, 451) = 1353 / 1353

GCD(3, 451) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 459

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

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

GCD(1, 459) = 459 / 459

GCD(1, 459) = 1

GCD of 393, 903, 451, 459 is 1
