Given Input Data is 819, 143, 664

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

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 143 is 11 x 13

Prime Factorization of 664 is 2 x 2 x 2 x 83

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(819, 143) = 9009

GCD(819, 143) = ( 819 x 143 ) / 9009

GCD(819, 143) = 117117 / 9009

GCD(819, 143) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 664

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

LCM(13, 664) = 8632

GCD(13, 664) = ( 13 x 664 ) / 8632

GCD(13, 664) = 8632 / 8632

GCD(13, 664) = 1

GCD of 819, 143, 664 is 1
