Therefore, GCD of numbers 844, 800, 861 is 1

Given Input Data is 844, 800, 861

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

Prime Factorization of 844 is 2 x 2 x 211

Prime Factorization of 800 is 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 861 is 3 x 7 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(844, 800) = 168800

GCD(844, 800) = ( 844 x 800 ) / 168800

GCD(844, 800) = 675200 / 168800

GCD(844, 800) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 861

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

LCM(4, 861) = 3444

GCD(4, 861) = ( 4 x 861 ) / 3444

GCD(4, 861) = 3444 / 3444

GCD(4, 861) = 1

GCD of 844, 800, 861 is 1
