Therefore, GCD of numbers 28, 372, 779, 831 is 1

Given Input Data is 28, 372, 779, 831

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 372 is 2 x 2 x 3 x 31

Prime Factorization of 779 is 19 x 41

Prime Factorization of 831 is 3 x 277

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, 372) = 2604

GCD(28, 372) = ( 28 x 372 ) / 2604

GCD(28, 372) = 10416 / 2604

GCD(28, 372) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 779

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

LCM(4, 779) = 3116

GCD(4, 779) = ( 4 x 779 ) / 3116

GCD(4, 779) = 3116 / 3116

GCD(4, 779) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 831

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

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

GCD(1, 831) = 831 / 831

GCD(1, 831) = 1

GCD of 28, 372, 779, 831 is 1
