Given Input Data is 981, 369, 555, 238

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

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 369 is 3 x 3 x 41

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 238 is 2 x 7 x 17

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(981, 369) = 40221

GCD(981, 369) = ( 981 x 369 ) / 40221

GCD(981, 369) = 361989 / 40221

GCD(981, 369) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 555

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

LCM(9, 555) = 1665

GCD(9, 555) = ( 9 x 555 ) / 1665

GCD(9, 555) = 4995 / 1665

GCD(9, 555) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 238

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

LCM(3, 238) = 714

GCD(3, 238) = ( 3 x 238 ) / 714

GCD(3, 238) = 714 / 714

GCD(3, 238) = 1

GCD of 981, 369, 555, 238 is 1
