Given Input Data is 720, 477, 256, 133

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

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

Prime Factorization of 477 is 3 x 3 x 53

Prime Factorization of 256 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 133 is 7 x 19

The above numbers do not have any common prime factor. So GCD is 1

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(720, 477) = 38160

GCD(720, 477) = ( 720 x 477 ) / 38160

GCD(720, 477) = 343440 / 38160

GCD(720, 477) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 256

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

LCM(9, 256) = 2304

GCD(9, 256) = ( 9 x 256 ) / 2304

GCD(9, 256) = 2304 / 2304

GCD(9, 256) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 133

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

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

GCD(1, 133) = 133 / 133

GCD(1, 133) = 1

GCD of 720, 477, 256, 133 is 1
