What are the multiplies of the number three?

Answer 1

3 6 9 12 15 18 21, etc.

Any number that is divisible by three, is a multiple of three. When working with larger numbers, try this shortcut: First add the digits together. If the sum of the digits is divisible by three, then the whole number is divisible by three.

For example:

5,844 (5 + 8 + 4 + 4 = 21). 21 is divisible by three; therefore, so is 5844. It is also a multiple three. This shortcut works with any whole number.
