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.
How can you use a divisibility rule to determine if117 is prime or composite?
By using the divisibility rule for 3, we find that 117 is divisible by 3. That makes it composite.
Determine if the number 79 is Prime or Composite?
It is a prime.
How can knowing the divisibility rules help to determine if a number is prime or composite?
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.

What are the determine number is a prime or composite of50?
10, 25, 50 are the composite factors of the composite number 50. 2 and 5 are prime.
Is 350 composite or prime?
350 is a composite number. it can be divisible by 10, 35, 5, 2 etc. You will find it easier to tell between prime and composite if you know the divisibility rules. one simple one is that if a number ends with zero it is divisible by 10...there are a lot of other divisibility rules.
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.
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.
How can you determine what numbers are prime or composite?
If the number can be multiplied by any number other than 1 it is a composite any other is prime
Determine if the given number is prime if the number is composite write it has a prime factor 295?
295 is composite - 5 x 59.
How can you use arrays to determine if a number prime or composite?
Yes
How do you figure out a composite number?
A number can be factored to determine whether it is prime or composite. A prime number has exactly 2 factors, 1 and the number itself. A composite number has more than two factors.
