First a little Freshen Up on this Chapter!

A factor(deler) is always smaller than the number.

1. True
2. False

Prime numbers always have 2 factors.
No less, no more.
True or False?

1. True
2. False

Explanation:

The statement is true, because that's what prime numbers are about!

For example: 13 is divisible only by 13 and by 1.

That makes it a prime number!
