Given Input Data is 863, 197, 255

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

Prime Factorization of 863 is 863

Prime Factorization of 197 is 197

Prime Factorization of 255 is 3 x 5 x 17

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(863, 197) = 170011

GCD(863, 197) = ( 863 x 197 ) / 170011

GCD(863, 197) = 170011 / 170011

GCD(863, 197) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 255

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

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

GCD(1, 255) = 255 / 255

GCD(1, 255) = 1

GCD of 863, 197, 255 is 1
