Given Input Data is 979, 420, 482, 412

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

Prime Factorization of 979 is 11 x 89

Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7

Prime Factorization of 482 is 2 x 241

Prime Factorization of 412 is 2 x 2 x 103

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, 420) = 411180

GCD(979, 420) = ( 979 x 420 ) / 411180

GCD(979, 420) = 411180 / 411180

GCD(979, 420) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 482

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

LCM(1, 482) = 482

GCD(1, 482) = ( 1 x 482 ) / 482

GCD(1, 482) = 482 / 482

GCD(1, 482) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 412

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

LCM(1, 412) = 412

GCD(1, 412) = ( 1 x 412 ) / 412

GCD(1, 412) = 412 / 412

GCD(1, 412) = 1

GCD of 979, 420, 482, 412 is 1
