Since all factors of 81 are odd, this is the same thing as asking what is the largest factor of 81, which is the same thing as asking what is the largest factor of any number. Since every number is a factor of itself, the answer is the number itself.

Now, had the question asked about proper factors, that would be a different story.

81, since 81 is odd and any number divides itself.
