Given Input Data is 979, 792, 389, 287

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

Prime Factorization of 979 is 11 x 89

Prime Factorization of 792 is 2 x 2 x 2 x 3 x 3 x 11

Prime Factorization of 389 is 389

Prime Factorization of 287 is 7 x 41

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, 792) = 70488

GCD(979, 792) = ( 979 x 792 ) / 70488

GCD(979, 792) = 775368 / 70488

GCD(979, 792) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 389

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

LCM(11, 389) = 4279

GCD(11, 389) = ( 11 x 389 ) / 4279

GCD(11, 389) = 4279 / 4279

GCD(11, 389) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 287

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

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

GCD(1, 287) = 287 / 287

GCD(1, 287) = 1

GCD of 979, 792, 389, 287 is 1
