Here is the C# Solution to find the factors of given number:

– To improve the Performance of finding Factors of a given Odd number, we can increment i in the for loop by 2 instead of 1.

 public List findFactors(int n)
            List factors = new List();

            int max = Convert.ToInt32(Math.Sqrt(n));

            for (int i = 1; i <= max; i++)
                if(n % i == 0)
                    if(i != max) // add square-root factors only once.
            return factors;
