I just turned age 36 (by Korean standards) and noticed that some of my friends seem to be sad to have such a "big" number as their age.
So I thought about whether there could be anything special about the number 36 and I found a simple and interesting pattern for that number.
When you divide 36 by 2, the answer is 18 (
36 / 2 == 18); and when you multiply each digit of 36 individually, the answer is also 18 (
3 * 6 == 18)!
So it seemed kind of special to me and then I wondered if there is any natural number that has these same features (except 0)
As a non-math person, the shocking discovery was that 36 seems to be the only number under 10M.
