Can a number have both and as factors? Can a number have both and as multiples? Can a number have both and as factors? Can a number have both and as multiples? Is there a general pattern here?
For each and below, is a factor of ? Explain how you know. (Notice that 3373 is a prime number!)

If you multiplied out the following number, how many zeroes would be at the end? (Don’t try this with your calculator!)

Hint: maybe try this with some smaller numbers first!

Let be the number you get if you multiply together twenty ’s, thirty ’s, and one . If you converted to a decimal, would the decimal terminate or repeat? (Don’t try this with your calculator!)

Hint #1: maybe try this with some smaller numbers first, like .

Hint #2: what does this question have to do with bundling?

What is the smallest number of steps you could take to determine whether or not is prime? How do you know?
Say that you have some number (maybe a little like 17, but not actually 17) which has a remainder of 2 when you divide by 5. And then say that you have some number (maybe a little like 23, but not actually 23) which has a remainder of 3 when you divide by 5. What would happen if you added , and then divided by 5? Does it matter what and are? Why or why not? What if you multiplied and divided by 5? Are there any other interesting questions you could ask, here?
