Given Input Data is 399, 981, 27, 181

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

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 181 is 181

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(399, 981) = 130473

GCD(399, 981) = ( 399 x 981 ) / 130473

GCD(399, 981) = 391419 / 130473

GCD(399, 981) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 27

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

LCM(3, 27) = 27

GCD(3, 27) = ( 3 x 27 ) / 27

GCD(3, 27) = 81 / 27

GCD(3, 27) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 181

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

LCM(3, 181) = 543

GCD(3, 181) = ( 3 x 181 ) / 543

GCD(3, 181) = 543 / 543

GCD(3, 181) = 1

GCD of 399, 981, 27, 181 is 1
