Given Input Data is 729, 897, 81, 223

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

Prime Factorization of 729 is 3 x 3 x 3 x 3 x 3 x 3

Prime Factorization of 897 is 3 x 13 x 23

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

Prime Factorization of 223 is 223

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(729, 897) = 217971

GCD(729, 897) = ( 729 x 897 ) / 217971

GCD(729, 897) = 653913 / 217971

GCD(729, 897) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 81

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

LCM(3, 81) = 81

GCD(3, 81) = ( 3 x 81 ) / 81

GCD(3, 81) = 243 / 81

GCD(3, 81) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 223

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

LCM(3, 223) = 669

GCD(3, 223) = ( 3 x 223 ) / 669

GCD(3, 223) = 669 / 669

GCD(3, 223) = 1

GCD of 729, 897, 81, 223 is 1
