Therefore, GCD of numbers 255, 115, 956, 285 is 1

Given Input Data is 255, 115, 956, 285

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

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 115 is 5 x 23

Prime Factorization of 956 is 2 x 2 x 239

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(255, 115) = 5865

GCD(255, 115) = ( 255 x 115 ) / 5865

GCD(255, 115) = 29325 / 5865

GCD(255, 115) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 956

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

LCM(5, 956) = 4780

GCD(5, 956) = ( 5 x 956 ) / 4780

GCD(5, 956) = 4780 / 4780

GCD(5, 956) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 285

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

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

GCD(1, 285) = 285 / 285

GCD(1, 285) = 1

GCD of 255, 115, 956, 285 is 1
