Given Input Data is 495, 630, 431, 397

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

Prime Factorization of 495 is 3 x 3 x 5 x 11

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 431 is 431

Prime Factorization of 397 is 397

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(495, 630) = 6930

GCD(495, 630) = ( 495 x 630 ) / 6930

GCD(495, 630) = 311850 / 6930

GCD(495, 630) = 45

Step2:

Here we consider the GCD from the above i.e. 45 as first number and the next as 431

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

LCM(45, 431) = 19395

GCD(45, 431) = ( 45 x 431 ) / 19395

GCD(45, 431) = 19395 / 19395

GCD(45, 431) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 397

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

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

GCD(1, 397) = 397 / 397

GCD(1, 397) = 1

GCD of 495, 630, 431, 397 is 1
