### Do all square numbers have an odd number of factors?

Yes, they do.
Factors come in pairs. When a number is squared it is only one
factor.
Example:
16
2x8 = 2 factors
4x4 = 1 factor
1x16 = 2 factors
Total = 5 factors
***
That's true of integers (whole numbers) that are perfect
squares.
It turns out that every whole number has an even number of
factors, but if the
number is a perfect square, then two of them are the same
number, so there
appear to be an odd number of them.
