However by looking at a number it is not easy to figure out whether a number is prime or composite.
Every even number excpet 2 is a composite number so, any number having last digit as 0, 2, 4, 6 or 8 is a composite number. This is one of the ways to figure out.
However for the odd numbers it becomes diificult to figure out.
For a quicker analysis there are divisiblity rules. These are shorthand ways to find whether a number is divisble by another without performing actual division.

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.
Can a number not be prime or composite?
Now.... That depends on whether it is a number orr not!? :)
What figure has a total number of sides that is a composite number?
Here are some figures that have a number of sides that is a composite number:Two-dimensional figures includesquarehexagonoctagonnonagonThree-dimensional figures includetetrahedroncubeoctahedronicosahedron
Can you tell a prime or composite number by seeing if its odd or even?
You cannot. If a number is even - other than 2 - then it is a composite number. However, if it is odd, it is not easily possible to tell whether it is prime or composite.
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.

To prove whether a number is composite, factor it. A number having any factor besides 1 and itself is composite.

In geometry what is a composite?
It is a geometric figure made from 2 or more other geometric figures, Similar to a composite number is one made of 2 or more primes. Make a "house" with a square and a triangle on top. This is a composite figure.
