Prime numbers are those numbers that can only be divided evenly by 1 and themselves. For example 7 cannot be divided evenly by 2, 3, 4, 5, or 6. It is prime. On the other hand 9, can be divided evenly by 3. Therefore it is not prime.
Yes, by these numbers: 1, 3, 17, 51.
Yes, by these numbers: 1, 3, 23, 69.
The common prime factors of 18 and 36 are 2 and 3. Both numbers can be divided evenly by 2 and 3.
63 is divided evenly by these numbers: 1, 3, 7, 9, 21, 63.
The only number that goes into both 3 and 4 evenly is 1.

1 and 3 both can.
Prime numbers can only be divided evenly by one and themselves, for example, 3 can only be divided evenly by 1 and 3, so it is prime. Composite numbers are evenly divisible by at least 3 numbers, such as 4 which is divisible by 1, 2 and 4.
Each of these numbers will go evenly into 18: 1, 2, 3, 6, 9, 18.
They are: 1 3 11 and 33
The number 6 is evenly divisible by the numbers 1, 2, 3, and 6. 6 divided by 1 = 6 6 divided by 2 = 3 6 divided by 3 = 2 6 divided by 6 = 1 All other numbers would not divide evenly.

No. Numbers that cannot be evenly divided into whole numbers are odd numbers. For example, 3 and 5 cannot be evenly divided- they are odd. 6 can be divided evenly into two threes- it is an even number.
63 is divided evenly by these numbers: 1, 3, 7, 9, 21, 63.
