Given Input Data is 861, 192, 451

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 192 is 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime Factorization of 451 is 11 x 41

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(861, 192) = 55104

GCD(861, 192) = ( 861 x 192 ) / 55104

GCD(861, 192) = 165312 / 55104

GCD(861, 192) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 451

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

LCM(3, 451) = 1353

GCD(3, 451) = ( 3 x 451 ) / 1353

GCD(3, 451) = 1353 / 1353

GCD(3, 451) = 1

GCD of 861, 192, 451 is 1
