Therefore, GCD of numbers 816, 220, 127 is 1

Given Input Data is 816, 220, 127

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

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

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

Prime Factorization of 127 is 127

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(816, 220) = 44880

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

GCD(816, 220) = 179520 / 44880

GCD(816, 220) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 127

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

LCM(4, 127) = 508

GCD(4, 127) = ( 4 x 127 ) / 508

GCD(4, 127) = 508 / 508

GCD(4, 127) = 1

GCD of 816, 220, 127 is 1
