Why does a perfect square always have an even number of factors?
You can always list the factors of a number, N, into pairs (ai, bi) where ai ≤ √N ≤ bi. This means that a number will always have an even number of factors, unless the number is a perfect square, in which case one pair will consists of the same two numbers.

Why does a square have odd number of factors?
Well, without the square root, the square no. would be even. Since the square root is multiplied by itself, then there is only 1 more factor, not 2. Example: 64. Has 6 factors (excluding 8 (squared)). With 8, there is now 7 factors… but not eight because the root (in this case, 8) will be repeated, and there is simply no point in repeating it.
