Given Input Data is 171, 663, 862

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

Prime Factorization of 171 is 3 x 3 x 19

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 862 is 2 x 431

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(171, 663) = 37791

GCD(171, 663) = ( 171 x 663 ) / 37791

GCD(171, 663) = 113373 / 37791

GCD(171, 663) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 862

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

LCM(3, 862) = 2586

GCD(3, 862) = ( 3 x 862 ) / 2586

GCD(3, 862) = 2586 / 2586

GCD(3, 862) = 1

GCD of 171, 663, 862 is 1
