The question does not make any sense at all because72 is not an odd number72 is not the largest factor of 720
Factors are any number that can be multiplied by another number to equal a different number. The largest odd factor is not defined because numbers can go up to infinity.
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.
The largest odd factor of 2011 is 2011.
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.
No odd number has an even factor.
I would call an odd number factor a factor that is an odd number. I would call a number with an odd number of factors a perfect square.
the largest odd number is 9
5 is an odd number and is a factor of 100
