Whatzit? Number Fun - 144 / (1 + 4 + 4) = 1*4*4

144 / (1 + 4 + 4) = 1*4*4

There is another 3digit number that works similarly: whatzit?

Simple python code found it:
[sp]

[FONT=Courier New]
for i in range(1,9):
    for j in range(1,9):
        for k in range(1,9):
            if 100*i + 10*j + k == i*j*k*(i + j + k):
                print(i,j,k)

It found 144 and 135. Those are the only ones!

Yepper!
Your code is exactly like mine; I use UBasic.

Tried with 2digit and 4digit numbers: none.

Spoiler

Erm... range(1,9) = (1,...,8) in python.
It's a good thing there are no numbers with a 9 in it!

Oops! How embarrassing.
