Recall that a factor of a number divides the original number and leaves no remainder. For example,

Find all factors of

. Remember that factors go together.

For example, ifgoes into exactly twice, then must go into exactly times.

This might help you go faster.Find the smallest number that has

, , , , and as factors. Because

is a factor, we know that it has to be a multiple of .

Becauseis also a factor, we know that the number has to be a multiple of .

Becauseis also a factor, we know that the number has to be a multiple of .

What is the first multiple ofthat is divisible by ? Find the second smallest number that has

, , , , and as factors. After reading the hint to part (b), answer the following question: What is the second multiple of

that is divisible by ?
