Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.

How do divisibility ryles help you to determine if a number is prime or composite?
If a number is divisible by 3 or more numbers than that number is composite, if not than it is prime.
How can your knowledge of divisibility rules help you to determine whether a number is prime or composite?
If a number is divisible by anything other than itself and 1, it's composite.
Can you use divisibility rules to find out if a number is prime or composite?
Yes you canYes. If a number is divisible by anything other than one or itself, it's composite.
How do you determine if a number is a composite number?
A composite number is a positive integer with more than two factors.
Is 400 a prime number or a composite number?
400 is a composite number because it is divisible by more than two numbers. Because it ends in a 0, the divisibility rules indicate it is divisible by 2, 5, and 10. (It is also divisible by other numbers.) It is not a prime number because a prime number has exactly two factors, 1 and itself.

Any even number is divisible by 2.
How can you determine whether one number is a factor of another?
Divide the smaller into the larger. If the quotient is an integer, the smaller is a factor of the larger.
Do you need to know all of the factors of a number in order to determine if it prime or composite?
No, you only need to determine if the number has any factors besides 1 and itself. If it does, it is a composite number.
