Is the greatest common factor if an odd number and an even number always even?
no. try 6 and 15. their GCF = 3 (odd)
Is the greatest common factor of any two odd numbers always odd?
Yes.Yes.2 can never be a factor of an odd number and because of that it can't be a common factor of any number pair where at least one of numbers is odd.
When multiplying an odd number by an odd number why is the result odd?
The product of multiplication results in a number that has all of the factors of the two numbers being multiplied. All even numbers have the prime factor 2. Since no odd number has the factor 2, no product of those numbers can have it. So: - Odd numbers times odd numbers produce odd numbers. - Odd numbers times even numbers produce even numbers. - Even numbers times even numbers produce even numbers.
What do you call an odd number 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.
