Given Input Data is 628, 230, 863, 872

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

Prime Factorization of 628 is 2 x 2 x 157

Prime Factorization of 230 is 2 x 5 x 23

Prime Factorization of 863 is 863

Prime Factorization of 872 is 2 x 2 x 2 x 109

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(628, 230) = 72220

GCD(628, 230) = ( 628 x 230 ) / 72220

GCD(628, 230) = 144440 / 72220

GCD(628, 230) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 863

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

LCM(2, 863) = 1726

GCD(2, 863) = ( 2 x 863 ) / 1726

GCD(2, 863) = 1726 / 1726

GCD(2, 863) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 872

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

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

GCD(1, 872) = 872 / 872

GCD(1, 872) = 1

GCD of 628, 230, 863, 872 is 1
