Yes. Square numbers have an odd number of factors. 49 has three factors.
Because 55 is an odd number. All the factors of odd numbers are odd.
Square numbers have an odd number of factors.
48 has both even and odd factors.
The number of factors can be either even or odd.
All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.
All nonzero numbers have factors. Some factors are odd numbers. The largest of these would be the greatest odd factor. Of course, the greatest odd factor of any odd number is the number itself.
Yes. An even number is defined as being evenly divisible by 2 (no fractional answers, only integers). If an odd number has an even factor, then because of the above definition, this odd number must have a factor of 2. But you will be hard pressed to find an odd number that is a multiple of 2, because that is already the definition of an even number. So, odd numbers cannot have even factors and thus odd numbers always have odd factors.
If the number is odd, that's the answer. If the number is even, write down all the factors and choose the largest one that is odd.

Yes, the factors of all odd numbers are odd numbers.

Square numbers have an odd number of factors, but beyond that, any odd number can be a factor.
No, and we doubt that you can either.
