Given Input Data is 392, 868, 72, 811

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

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 811 is 811

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(392, 868) = 12152

GCD(392, 868) = ( 392 x 868 ) / 12152

GCD(392, 868) = 340256 / 12152

GCD(392, 868) = 28

Step2:

Here we consider the GCD from the above i.e. 28 as first number and the next as 72

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

LCM(28, 72) = 504

GCD(28, 72) = ( 28 x 72 ) / 504

GCD(28, 72) = 2016 / 504

GCD(28, 72) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 811

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

LCM(4, 811) = 3244

GCD(4, 811) = ( 4 x 811 ) / 3244

GCD(4, 811) = 3244 / 3244

GCD(4, 811) = 1

GCD of 392, 868, 72, 811 is 1
