I would like all the members here take part in this and contribute to this simple thread......

We all think differently....so we ll have different solutions to this simple problem.

I am searching for different logics that would generate the following numbers in an arbitary range say between UpperLimit and LowerLimit. (int UL,LL).

1. Armstrong Number

*2. Magic / Ramanujan Number [http://www.quickermaths.com/ramanujan-number/] << This is more important for me.

3. Krishnamurthy Number [A krishnamurthy number is one whose sum of the factorials of each number is equal to the number itself. Eg: 145]
