Therefore, GCD of numbers 905, 865, 935, 231 is 1

Given Input Data is 905, 865, 935, 231

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

Prime Factorization of 905 is 5 x 181

Prime Factorization of 865 is 5 x 173

Prime Factorization of 935 is 5 x 11 x 17

Prime Factorization of 231 is 3 x 7 x 11

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(905, 865) = 156565

GCD(905, 865) = ( 905 x 865 ) / 156565

GCD(905, 865) = 782825 / 156565

GCD(905, 865) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 935

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

LCM(5, 935) = 935

GCD(5, 935) = ( 5 x 935 ) / 935

GCD(5, 935) = 4675 / 935

GCD(5, 935) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 231

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

LCM(5, 231) = 1155

GCD(5, 231) = ( 5 x 231 ) / 1155

GCD(5, 231) = 1155 / 1155

GCD(5, 231) = 1

GCD of 905, 865, 935, 231 is 1
