Given Input Data is 979, 330, 990, 247

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

Prime Factorization of 979 is 11 x 89

Prime Factorization of 330 is 2 x 3 x 5 x 11

Prime Factorization of 990 is 2 x 3 x 3 x 5 x 11

Prime Factorization of 247 is 13 x 19

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(979, 330) = 29370

GCD(979, 330) = ( 979 x 330 ) / 29370

GCD(979, 330) = 323070 / 29370

GCD(979, 330) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 990

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

LCM(11, 990) = 990

GCD(11, 990) = ( 11 x 990 ) / 990

GCD(11, 990) = 10890 / 990

GCD(11, 990) = 11

Step3:

Here we consider the GCD from the above i.e. 11 as first number and the next as 247

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

LCM(11, 247) = 2717

GCD(11, 247) = ( 11 x 247 ) / 2717

GCD(11, 247) = 2717 / 2717

GCD(11, 247) = 1

GCD of 979, 330, 990, 247 is 1
