Given Input Data is 646, 494, 474, 629

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 494 is 2 x 13 x 19

Prime Factorization of 474 is 2 x 3 x 79

Prime Factorization of 629 is 17 x 37

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(646, 494) = 8398

GCD(646, 494) = ( 646 x 494 ) / 8398

GCD(646, 494) = 319124 / 8398

GCD(646, 494) = 38

Step2:

Here we consider the GCD from the above i.e. 38 as first number and the next as 474

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

LCM(38, 474) = 9006

GCD(38, 474) = ( 38 x 474 ) / 9006

GCD(38, 474) = 18012 / 9006

GCD(38, 474) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 629

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

LCM(2, 629) = 1258

GCD(2, 629) = ( 2 x 629 ) / 1258

GCD(2, 629) = 1258 / 1258

GCD(2, 629) = 1

GCD of 646, 494, 474, 629 is 1
