Given Input Data is 765, 813, 473, 210

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

Prime Factorization of 765 is 3 x 3 x 5 x 17

Prime Factorization of 813 is 3 x 271

Prime Factorization of 473 is 11 x 43

Prime Factorization of 210 is 2 x 3 x 5 x 7

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(765, 813) = 207315

GCD(765, 813) = ( 765 x 813 ) / 207315

GCD(765, 813) = 621945 / 207315

GCD(765, 813) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 473

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

LCM(3, 473) = 1419

GCD(3, 473) = ( 3 x 473 ) / 1419

GCD(3, 473) = 1419 / 1419

GCD(3, 473) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 210

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

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

GCD(1, 210) = 210 / 210

GCD(1, 210) = 1

GCD of 765, 813, 473, 210 is 1
