Given Input Data is 905, 435, 865, 881

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

Prime Factorization of 905 is 5 x 181

Prime Factorization of 435 is 3 x 5 x 29

Prime Factorization of 865 is 5 x 173

Prime Factorization of 881 is 881

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, 435) = 78735

GCD(905, 435) = ( 905 x 435 ) / 78735

GCD(905, 435) = 393675 / 78735

GCD(905, 435) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 865

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

LCM(5, 865) = 865

GCD(5, 865) = ( 5 x 865 ) / 865

GCD(5, 865) = 4325 / 865

GCD(5, 865) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 881

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

LCM(5, 881) = 4405

GCD(5, 881) = ( 5 x 881 ) / 4405

GCD(5, 881) = 4405 / 4405

GCD(5, 881) = 1

GCD of 905, 435, 865, 881 is 1
