What is the smallest number greater than 100 that is:

a) divisible by two?

b) divisible by ten?

c) divisible by four?

I'd start by listing out the multiplies of all three past 100, like this:

102, 104, 106, 108, 110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 130

104, 108, 112, 116, 120, 124, 128, 132, 136

110, 120, 130, 140

Now it's just a matter of finding the number that is the same for all three of them, which is 120.

The smallest number greater than 100 is divisible by ten
