Given Input Data is 865, 255, 45, 857

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

Prime Factorization of 865 is 5 x 173

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 857 is 857

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(865, 255) = 44115

GCD(865, 255) = ( 865 x 255 ) / 44115

GCD(865, 255) = 220575 / 44115

GCD(865, 255) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 45

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

LCM(5, 45) = 45

GCD(5, 45) = ( 5 x 45 ) / 45

GCD(5, 45) = 225 / 45

GCD(5, 45) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 857

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

LCM(5, 857) = 4285

GCD(5, 857) = ( 5 x 857 ) / 4285

GCD(5, 857) = 4285 / 4285

GCD(5, 857) = 1

GCD of 865, 255, 45, 857 is 1
