Given Input Data is 220, 816, 571

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

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 816 is 2 x 2 x 2 x 2 x 3 x 17

Prime Factorization of 571 is 571

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(220, 816) = 44880

GCD(220, 816) = ( 220 x 816 ) / 44880

GCD(220, 816) = 179520 / 44880

GCD(220, 816) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 571

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

LCM(4, 571) = 2284

GCD(4, 571) = ( 4 x 571 ) / 2284

GCD(4, 571) = 2284 / 2284

GCD(4, 571) = 1

GCD of 220, 816, 571 is 1
