Therefore, GCD of numbers 300, 512, 861 is 1

Given Input Data is 300, 512, 861

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

Prime Factorization of 300 is 2 x 2 x 3 x 5 x 5

Prime Factorization of 512 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

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(300, 512) = 38400

GCD(300, 512) = ( 300 x 512 ) / 38400

GCD(300, 512) = 153600 / 38400

GCD(300, 512) = 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 300, 512, 861 is 1
