Therefore, GCD of numbers 255, 249, 817, 469 is 1

Given Input Data is 255, 249, 817, 469

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 249 is 3 x 83

Prime Factorization of 817 is 19 x 43

Prime Factorization of 469 is 7 x 67

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, 249) = 21165

GCD(255, 249) = ( 255 x 249 ) / 21165

GCD(255, 249) = 63495 / 21165

GCD(255, 249) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 817

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

LCM(3, 817) = 2451

GCD(3, 817) = ( 3 x 817 ) / 2451

GCD(3, 817) = 2451 / 2451

GCD(3, 817) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 469

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

LCM(1, 469) = 469

GCD(1, 469) = ( 1 x 469 ) / 469

GCD(1, 469) = 469 / 469

GCD(1, 469) = 1

GCD of 255, 249, 817, 469 is 1
