Given Input Data is 570, 195, 470, 487

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

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 470 is 2 x 5 x 47

Prime Factorization of 487 is 487

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(570, 195) = 7410

GCD(570, 195) = ( 570 x 195 ) / 7410

GCD(570, 195) = 111150 / 7410

GCD(570, 195) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 470

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

LCM(15, 470) = 1410

GCD(15, 470) = ( 15 x 470 ) / 1410

GCD(15, 470) = 7050 / 1410

GCD(15, 470) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 487

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

LCM(5, 487) = 2435

GCD(5, 487) = ( 5 x 487 ) / 2435

GCD(5, 487) = 2435 / 2435

GCD(5, 487) = 1

GCD of 570, 195, 470, 487 is 1
