It’s a poorly worded question. We’ll need a lawyer to figure out whether it means that the consecutive odd factors are the only factors or that they are two of the factors and that there could be others. I’m inclined to think that the question writer did not intend to “confuse” or “trick” the test taker. This is a math problem and not a CR problem after all.

So:

The factors are 2n+1 and 2n+3, where n is equal or greater than zero,
and N=(2n+1)*(2n+3)<400, or n=0, 1, …, 9.
