Therefore, GCD of numbers 819, 406, 487, 583 is 1

Given Input Data is 819, 406, 487, 583

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

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 487 is 487

Prime Factorization of 583 is 11 x 53

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(819, 406) = 47502

GCD(819, 406) = ( 819 x 406 ) / 47502

GCD(819, 406) = 332514 / 47502

GCD(819, 406) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 487

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

LCM(7, 487) = 3409

GCD(7, 487) = ( 7 x 487 ) / 3409

GCD(7, 487) = 3409 / 3409

GCD(7, 487) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 583

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

LCM(1, 583) = 583

GCD(1, 583) = ( 1 x 583 ) / 583

GCD(1, 583) = 583 / 583

GCD(1, 583) = 1

GCD of 819, 406, 487, 583 is 1
