Given Input Data is 855, 865, 259

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

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 865 is 5 x 173

Prime Factorization of 259 is 7 x 37

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(855, 865) = 147915

GCD(855, 865) = ( 855 x 865 ) / 147915

GCD(855, 865) = 739575 / 147915

GCD(855, 865) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 259

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

LCM(5, 259) = 1295

GCD(5, 259) = ( 5 x 259 ) / 1295

GCD(5, 259) = 1295 / 1295

GCD(5, 259) = 1

GCD of 855, 865, 259 is 1
