Given Input Data is 980, 304, 489

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

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 304 is 2 x 2 x 2 x 2 x 19

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(980, 304) = 74480

GCD(980, 304) = ( 980 x 304 ) / 74480

GCD(980, 304) = 297920 / 74480

GCD(980, 304) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 489

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

LCM(4, 489) = 1956

GCD(4, 489) = ( 4 x 489 ) / 1956

GCD(4, 489) = 1956 / 1956

GCD(4, 489) = 1

GCD of 980, 304, 489 is 1
