Therefore, GCD of numbers 816, 312, 781, 818 is 1

Given Input Data is 816, 312, 781, 818

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

Prime Factorization of 816 is 2 x 2 x 2 x 2 x 3 x 17

Prime Factorization of 312 is 2 x 2 x 2 x 3 x 13

Prime Factorization of 781 is 11 x 71

Prime Factorization of 818 is 2 x 409

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(816, 312) = 10608

GCD(816, 312) = ( 816 x 312 ) / 10608

GCD(816, 312) = 254592 / 10608

GCD(816, 312) = 24

Step2:

Here we consider the GCD from the above i.e. 24 as first number and the next as 781

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

LCM(24, 781) = 18744

GCD(24, 781) = ( 24 x 781 ) / 18744

GCD(24, 781) = 18744 / 18744

GCD(24, 781) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 818

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

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

GCD(1, 818) = 818 / 818

GCD(1, 818) = 1

GCD of 816, 312, 781, 818 is 1
