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.
In mathematics, numbers that can be divided without a remainder are referred to as divisible numbers. For example, any integer can be divided by its factors, such as 2, 3, or 5, if those numbers evenly divide it. Additionally, whole numbers can be divided by themselves and 1 without a remainder. Essentially, any number can be divided evenly by its divisors.

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.
Use Number sense Write 2 numbers that cannot be divided evenly by 8 or 9.
They are: 1 3 11 and 33
Each of these numbers will go evenly into 18: 1, 2, 3, 6, 9, 18.
Numbers that can be divided evenly by both 3 and 7 must be multiples of the least common multiple of 3 and 7, which is 21. Therefore, any number that is a multiple of 21 can be divided by both 3 and 7. Examples of such numbers include 21, 42, 63, 84, and so on.
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.
