I want to find a number that is divisible by three. I also want all of its digits to be 8s. Does my number exist?

Scroll down for the answer!

Yes! If you add the digits of a number together and they are divisible by three, the original number is also divisible by three.

8 + 8 + 8 = 24 and 24 is divisible by three, so 888 is a solution to the puzzle!

There are also other solutions, including 888 888 and 888 888 888.
