Given Input Data is 468, 558, 720, 340

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

Prime Factorization of 468 is 2 x 2 x 3 x 3 x 13

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime Factorization of 340 is 2 x 2 x 5 x 17

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(468, 558) = 14508

GCD(468, 558) = ( 468 x 558 ) / 14508

GCD(468, 558) = 261144 / 14508

GCD(468, 558) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 720

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

LCM(18, 720) = 720

GCD(18, 720) = ( 18 x 720 ) / 720

GCD(18, 720) = 12960 / 720

GCD(18, 720) = 18

Step3:

Here we consider the GCD from the above i.e. 18 as first number and the next as 340

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

LCM(18, 340) = 3060

GCD(18, 340) = ( 18 x 340 ) / 3060

GCD(18, 340) = 6120 / 3060

GCD(18, 340) = 2

GCD of 468, 558, 720, 340 is 2
