Given Input Data is 66, 308, 294, 622

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 308 is 2 x 2 x 7 x 11

Prime Factorization of 294 is 2 x 3 x 7 x 7

Prime Factorization of 622 is 2 x 311

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(66, 308) = 924

GCD(66, 308) = ( 66 x 308 ) / 924

GCD(66, 308) = 20328 / 924

GCD(66, 308) = 22

Step2:

Here we consider the GCD from the above i.e. 22 as first number and the next as 294

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

LCM(22, 294) = 3234

GCD(22, 294) = ( 22 x 294 ) / 3234

GCD(22, 294) = 6468 / 3234

GCD(22, 294) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 622

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

LCM(2, 622) = 622

GCD(2, 622) = ( 2 x 622 ) / 622

GCD(2, 622) = 1244 / 622

GCD(2, 622) = 2

GCD of 66, 308, 294, 622 is 2
