Given Input Data is 81, 786, 249, 206

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

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 786 is 2 x 3 x 131

Prime Factorization of 249 is 3 x 83

Prime Factorization of 206 is 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(81, 786) = 21222

GCD(81, 786) = ( 81 x 786 ) / 21222

GCD(81, 786) = 63666 / 21222

GCD(81, 786) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 249

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

LCM(3, 249) = 249

GCD(3, 249) = ( 3 x 249 ) / 249

GCD(3, 249) = 747 / 249

GCD(3, 249) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 206

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

LCM(3, 206) = 618

GCD(3, 206) = ( 3 x 206 ) / 618

GCD(3, 206) = 618 / 618

GCD(3, 206) = 1

GCD of 81, 786, 249, 206 is 1
