Will an odd number ever have even numbers in its exponential form?
All even numbers have 2 as a factor, but no odd numbers do. The only even number that will appear as a factor in prime factorizations is 2, because it is the only even prime number. Thus, an odd number will not have even numbers in its prime factorization because an odd number is not evenly divisible by 2. The only even numbers that could appear in the exponential form are the exponents. For example 81 is 34. The factor is an odd number - 3, while the exponent is an even number - 4.
Is the greatest common factor an odd number and even number is always even?
No. Odd numbers only have odd factors. They could not have an even factor in common.
How do you find highest odd factor of a number?
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.
What type of factor has an odd number of factors?
A perfect square has an odd number of factors.
Is 2 a factor of 255?
No. 255 is an odd number.
