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.

BlakeNo, the factors of an odd number are not always odd. An odd number is defined as a number that cannot be evenly divided by 2. Therefore, the factors of an odd number can be odd or even. For example, the factors of the odd number 15 are 1, 3, 5, and 15, which include both odd and even numbers.
Oh, dude, let me drop some knowledge on you. So, an odd number can totally have odd factors, but it can also have some sneaky even factors too. Like, take the number 9, it's odd, right? But it's got 1, 3, and 9 as factors, which are all odd, but then it's also got 2 as a factor, which is even. So, yeah, odd numbers can have a mix of odd and even factors, just keeping us on our toes, you know?
Yes, the factors of an odd number are always odd. this is because, even * anything = even. Always. So, we can never get an odd number by multiplying something in an even number. which means factors of odd number are always odd.
For example, 21 is odd. so factors of 21 are = { 1, 3, 7, 21 }. all of which are odd numbers.

Is the product of an odd number of factors always a negative number?
Only if an odd number of the factors are negative numbers.
Is the gcf of an odd and even number always even?
No. The opposite is true: the gcf of an odd number and an even number is always odd. All the factors of an odd number are odd; or to put it another way: If a number has an even factor, the number itself must be even. Thus the only common factors between odd and even numbers must be odd.
What happens when you add an odd number and an odd number?
Two odd numbers always sum to an even number. Always. Two even numbers always sum to an even number, and an odd number and an even number always sum to an odd number.
What does odd divided by odd always equal?
The result will always be an odd number.
Are the factors of an even number always even?
i dont think so because 3 is an odd number but it can go into 12 :] hope i helped
