Therefore, GCD of numbers 618, 255, 485, 811 is 1

Given Input Data is 618, 255, 485, 811

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

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 485 is 5 x 97

Prime Factorization of 811 is 811

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(618, 255) = 52530

GCD(618, 255) = ( 618 x 255 ) / 52530

GCD(618, 255) = 157590 / 52530

GCD(618, 255) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 485

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

LCM(3, 485) = 1455

GCD(3, 485) = ( 3 x 485 ) / 1455

GCD(3, 485) = 1455 / 1455

GCD(3, 485) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

GCD of 618, 255, 485, 811 is 1
