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.
Only perfect squares can have an odd number of factors. The answer is 16. It has five factors: 1,2,4,8,16.
No numbers in that range have an odd number of factors.
Only if an odd number of the factors are negative numbers.
Both odd and even numbers may have odd numbers as factors.
The number of factors can be either even or odd.
1610025 = 3*5*5*21467 has 12 factors and 12 is NOT an odd number.
All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.
That's just as meaningless a question as asking "what is the biggest number?" Just as there is no biggest number (you can always get bigger numbers by adding 1), there is no odd number with the most factors. You could multiply any odd number by 3, and get an odd number with another factor of 3.
No. The number 57 has an even number of factors. They are: 1, 3, 19, 57.

Square numbers have an odd number of factors.
Square numbers have an odd number of factors.
Yes. Square numbers have an odd number of factors. 49 has three factors.
Yes, quare numbers have an odd number of factors.
if a number has an odd number of factors it would be a perfect square
if a number has an odd number of factors it would be a perfect square
