Therefore, GCD of numbers 28, 595, 818, 477 is 1

Given Input Data is 28, 595, 818, 477

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 595 is 5 x 7 x 17

Prime Factorization of 818 is 2 x 409

Prime Factorization of 477 is 3 x 3 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(28, 595) = 2380

GCD(28, 595) = ( 28 x 595 ) / 2380

GCD(28, 595) = 16660 / 2380

GCD(28, 595) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 818

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

LCM(7, 818) = 5726

GCD(7, 818) = ( 7 x 818 ) / 5726

GCD(7, 818) = 5726 / 5726

GCD(7, 818) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 477

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

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

GCD(1, 477) = 477 / 477

GCD(1, 477) = 1

GCD of 28, 595, 818, 477 is 1
