Any number that you get when you multiply it by four is considered a multiple of four so 8, 12, 16, 20, 24, 28 and 32 are all examples of multiples of four.
If the last two digits of a number is divisible by four, then the number is divisible by four. This works because 100 = 4 times 25. Examples of four digit mutiples of four are one thousand,
twelve hundred thirty two, sixteen hundred sixty four, four thousand forty four, and five thousand one hundred seventy two.
