Given Input Data is 795, 640, 831

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

Prime Factorization of 795 is 3 x 5 x 53

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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(795, 640) = 101760

GCD(795, 640) = ( 795 x 640 ) / 101760

GCD(795, 640) = 508800 / 101760

GCD(795, 640) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 831

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

LCM(5, 831) = 4155

GCD(5, 831) = ( 5 x 831 ) / 4155

GCD(5, 831) = 4155 / 4155

GCD(5, 831) = 1

GCD of 795, 640, 831 is 1
