Given Input Data is 782, 323, 303, 865

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

Prime Factorization of 782 is 2 x 17 x 23

Prime Factorization of 323 is 17 x 19

Prime Factorization of 303 is 3 x 101

Prime Factorization of 865 is 5 x 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(782, 323) = 14858

GCD(782, 323) = ( 782 x 323 ) / 14858

GCD(782, 323) = 252586 / 14858

GCD(782, 323) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 303

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

LCM(17, 303) = 5151

GCD(17, 303) = ( 17 x 303 ) / 5151

GCD(17, 303) = 5151 / 5151

GCD(17, 303) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 865

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

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

GCD(1, 865) = 865 / 865

GCD(1, 865) = 1

GCD of 782, 323, 303, 865 is 1
