Composite Numbers



Definition
A number which has more factors (other than itself and 1) is called Composite number.
In other words, all Natural Numbers other than Prime Numbers are known Composite Numbers.

Note:- 1 is neither a prime number nor a composite number

Read the following examples to learn Composite Numbers.

Example 1 = Explain whether given natural number 24 is a composite number or not ?
Answer = Find factors of given natural number 24.
Factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24.
Since, the given natural number 24 has more factors (other than itself and 1),
we can say that the given natural number 24 is a Composite Number.

Example 2 = Explain whether given natural number 13 is a composite number or not ?
Answer = Find factors of given natural number 13.
Factors of 13 = 1 and 13.
Since, the given natural number 13 has no factor; other than itself and 1.
we can say that the given natural number 13 is not a Composite Number; but it is a Prime number.

Example 3 = Explain whether given natural number 27 is a composite number or not ?
Answer = Find factors of given natural number 27.
Factors of 27 = 1, 3, 9 and 7
Since, the given natural number 27 has more factors (other than itself and 1),
we can say that the given natural number 27 is a Composite Number.
