Given Input Data is 646, 935, 394, 489

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 935 is 5 x 11 x 17

Prime Factorization of 394 is 2 x 197

Prime Factorization of 489 is 3 x 163

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, 935) = 35530

GCD(646, 935) = ( 646 x 935 ) / 35530

GCD(646, 935) = 604010 / 35530

GCD(646, 935) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 394

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

LCM(17, 394) = 6698

GCD(17, 394) = ( 17 x 394 ) / 6698

GCD(17, 394) = 6698 / 6698

GCD(17, 394) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 489

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

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

GCD(1, 489) = 489 / 489

GCD(1, 489) = 1

GCD of 646, 935, 394, 489 is 1
