Given Input Data is 255, 798, 87, 181

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 798 is 2 x 3 x 7 x 19

Prime Factorization of 87 is 3 x 29

Prime Factorization of 181 is 181

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, 798) = 67830

GCD(255, 798) = ( 255 x 798 ) / 67830

GCD(255, 798) = 203490 / 67830

GCD(255, 798) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 87

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

LCM(3, 87) = 87

GCD(3, 87) = ( 3 x 87 ) / 87

GCD(3, 87) = 261 / 87

GCD(3, 87) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 181

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

LCM(3, 181) = 543

GCD(3, 181) = ( 3 x 181 ) / 543

GCD(3, 181) = 543 / 543

GCD(3, 181) = 1

GCD of 255, 798, 87, 181 is 1
