Therefore, GCD of numbers 578, 459, 40, 313 is 1

Given Input Data is 578, 459, 40, 313

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

Prime Factorization of 578 is 2 x 17 x 17

Prime Factorization of 459 is 3 x 3 x 3 x 17

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 313 is 313

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(578, 459) = 15606

GCD(578, 459) = ( 578 x 459 ) / 15606

GCD(578, 459) = 265302 / 15606

GCD(578, 459) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 40

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

LCM(17, 40) = 680

GCD(17, 40) = ( 17 x 40 ) / 680

GCD(17, 40) = 680 / 680

GCD(17, 40) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 313

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

LCM(1, 313) = 313

GCD(1, 313) = ( 1 x 313 ) / 313

GCD(1, 313) = 313 / 313

GCD(1, 313) = 1

GCD of 578, 459, 40, 313 is 1
