Given Input Data is 255, 310, 549, 605

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 310 is 2 x 5 x 31

Prime Factorization of 549 is 3 x 3 x 61

Prime Factorization of 605 is 5 x 11 x 11

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, 310) = 15810

GCD(255, 310) = ( 255 x 310 ) / 15810

GCD(255, 310) = 79050 / 15810

GCD(255, 310) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 549

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

LCM(5, 549) = 2745

GCD(5, 549) = ( 5 x 549 ) / 2745

GCD(5, 549) = 2745 / 2745

GCD(5, 549) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 605

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

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

GCD(1, 605) = 605 / 605

GCD(1, 605) = 1

GCD of 255, 310, 549, 605 is 1
