No. 24 has 3 as a factor. 30 has 15 as a factor.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a factor of 9. 3 is a factor of 15. 3 is a common factor of 9 and 15.
That's an infinite list.
All of them are prime numbers
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a common factor of 9 and 12.
There are an infinite number of numbers with 3 as a factor. Any number evenly divisible by 3 has 3 as a factor. That means 6, 9, 12, 15, 18, ..., all have 3 as a factor.
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.

All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors because they are factors that the numbers have in common. 3 is a factor of 12. 3 is a factor of 15. 3 is a common factor of 12 and 15.
No. Seven is odd, for example, and does not have three as a factor.
Since all numbers have one as a factor, there is no number with three as its only factor.
All of them.
All of them are prime numbers
All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.
