Given Input Data is 285, 504, 121

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

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 504 is 2 x 2 x 2 x 3 x 3 x 7

Prime Factorization of 121 is 11 x 11

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(285, 504) = 47880

GCD(285, 504) = ( 285 x 504 ) / 47880

GCD(285, 504) = 143640 / 47880

GCD(285, 504) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 121

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

LCM(3, 121) = 363

GCD(3, 121) = ( 3 x 121 ) / 363

GCD(3, 121) = 363 / 363

GCD(3, 121) = 1

GCD of 285, 504, 121 is 1
