No. Seven is odd, for example, and does not have three as a factor.

How do you find an odd factor of a number?

All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.

Is three a factor of all odd numbers?

No. A few counterexamples include the numbers 1, 5, 7, and 11, which are all odd numbers but of which 3 is not a factor.

Odd numbers with a multiple of 3 and not a factor of 8?

All odd multiples of 3 are not factors of 8.

What odd whole numbers have 12 as a factor?

No odd whole numbers have 12 as a factor. 1 and 3 are odd numbers that are factors of 12.

Are all odd numbers relatively prime numbers?

No. For example: 9 and 27 are both odd but not relatively prime (they both have the factor 3).

What are numbers that have no common factors?

Since one is a factor of all non-zero integers, all numbers have common factors.

What is the greatest common factor of any two odd numbers?

This can't be determined. The GCF of 3 and 5 is 1. The GCF of 11 and 33 is 11. There's no rule that covers any and all odd numbers.

The only number between 3 and 45 which is a factor of 3 is 3. There are several multiples of 3 beyond this.

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.
