Given Input Data is 806, 286, 198, 830

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

Prime Factorization of 806 is 2 x 13 x 31

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 198 is 2 x 3 x 3 x 11

Prime Factorization of 830 is 2 x 5 x 83

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(806, 286) = 8866

GCD(806, 286) = ( 806 x 286 ) / 8866

GCD(806, 286) = 230516 / 8866

GCD(806, 286) = 26

Step2:

Here we consider the GCD from the above i.e. 26 as first number and the next as 198

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

LCM(26, 198) = 2574

GCD(26, 198) = ( 26 x 198 ) / 2574

GCD(26, 198) = 5148 / 2574

GCD(26, 198) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 830

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

LCM(2, 830) = 830

GCD(2, 830) = ( 2 x 830 ) / 830

GCD(2, 830) = 1660 / 830

GCD(2, 830) = 2

GCD of 806, 286, 198, 830 is 2
