Therefore, GCD of numbers 905, 117, 865 is 1

Given Input Data is 905, 117, 865

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

Prime Factorization of 905 is 5 x 181

Prime Factorization of 117 is 3 x 3 x 13

Prime Factorization of 865 is 5 x 173

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, 117) = 105885

GCD(905, 117) = ( 905 x 117 ) / 105885

GCD(905, 117) = 105885 / 105885

GCD(905, 117) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 865

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

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

GCD(1, 865) = 865 / 865

GCD(1, 865) = 1

GCD of 905, 117, 865 is 1
