Therefore, GCD of numbers 927, 906, 81, 721 is 1

Given Input Data is 927, 906, 81, 721

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

Prime Factorization of 927 is 3 x 3 x 103

Prime Factorization of 906 is 2 x 3 x 151

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

Prime Factorization of 721 is 7 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(927, 906) = 279954

GCD(927, 906) = ( 927 x 906 ) / 279954

GCD(927, 906) = 839862 / 279954

GCD(927, 906) = 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 721

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

LCM(3, 721) = 2163

GCD(3, 721) = ( 3 x 721 ) / 2163

GCD(3, 721) = 2163 / 2163

GCD(3, 721) = 1

GCD of 927, 906, 81, 721 is 1
