Given Input Data is 813, 831, 633

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

Prime Factorization of 813 is 3 x 271

Prime Factorization of 831 is 3 x 277

Prime Factorization of 633 is 3 x 211

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(813, 831) = 225201

GCD(813, 831) = ( 813 x 831 ) / 225201

GCD(813, 831) = 675603 / 225201

GCD(813, 831) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 633

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

LCM(3, 633) = 633

GCD(3, 633) = ( 3 x 633 ) / 633

GCD(3, 633) = 1899 / 633

GCD(3, 633) = 3

GCD of 813, 831, 633 is 3
