Given Input Data is 20, 888, 772, 285

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 888 is 2 x 2 x 2 x 3 x 37

Prime Factorization of 772 is 2 x 2 x 193

Prime Factorization of 285 is 3 x 5 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(20, 888) = 4440

GCD(20, 888) = ( 20 x 888 ) / 4440

GCD(20, 888) = 17760 / 4440

GCD(20, 888) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 772

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

LCM(4, 772) = 772

GCD(4, 772) = ( 4 x 772 ) / 772

GCD(4, 772) = 3088 / 772

GCD(4, 772) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 285

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

LCM(4, 285) = 1140

GCD(4, 285) = ( 4 x 285 ) / 1140

GCD(4, 285) = 1140 / 1140

GCD(4, 285) = 1

GCD of 20, 888, 772, 285 is 1
