Therefore, GCD of numbers 558, 663, 811, 287 is 1

Given Input Data is 558, 663, 811, 287

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

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 811 is 811

Prime Factorization of 287 is 7 x 41

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(558, 663) = 123318

GCD(558, 663) = ( 558 x 663 ) / 123318

GCD(558, 663) = 369954 / 123318

GCD(558, 663) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 811

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

LCM(3, 811) = 2433

GCD(3, 811) = ( 3 x 811 ) / 2433

GCD(3, 811) = 2433 / 2433

GCD(3, 811) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 287

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

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

GCD(1, 287) = 287 / 287

GCD(1, 287) = 1

GCD of 558, 663, 811, 287 is 1
