Given Input Data is 105, 476, 489, 298

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

Prime Factorization of 105 is 3 x 5 x 7

Prime Factorization of 476 is 2 x 2 x 7 x 17

Prime Factorization of 489 is 3 x 163

Prime Factorization of 298 is 2 x 149

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(105, 476) = 7140

GCD(105, 476) = ( 105 x 476 ) / 7140

GCD(105, 476) = 49980 / 7140

GCD(105, 476) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 489

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

LCM(7, 489) = 3423

GCD(7, 489) = ( 7 x 489 ) / 3423

GCD(7, 489) = 3423 / 3423

GCD(7, 489) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 298

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

LCM(1, 298) = 298

GCD(1, 298) = ( 1 x 298 ) / 298

GCD(1, 298) = 298 / 298

GCD(1, 298) = 1

GCD of 105, 476, 489, 298 is 1
