Given Input Data is 260, 830, 406, 492

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

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 492 is 2 x 2 x 3 x 41

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(260, 830) = 21580

GCD(260, 830) = ( 260 x 830 ) / 21580

GCD(260, 830) = 215800 / 21580

GCD(260, 830) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 406

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

LCM(10, 406) = 2030

GCD(10, 406) = ( 10 x 406 ) / 2030

GCD(10, 406) = 4060 / 2030

GCD(10, 406) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 492

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

LCM(2, 492) = 492

GCD(2, 492) = ( 2 x 492 ) / 492

GCD(2, 492) = 984 / 492

GCD(2, 492) = 2

GCD of 260, 830, 406, 492 is 2
