The Number 37 And Its Magic

There is a three-factor in this one.

Multiply 37 by 3, and you have 111.

37 x 3 = 111

Jump up three numbers to 6, and mutliply by 37 again.

You have 222.

37 x 6 = 222

Three more and you are at 9.

Multiply by 37 again and you have 333.

37 x 9 = 333

This "jumpupthree" routine works all the way up to 27 

(27 x 37 = 999).

After that, 37 loses its magic.
