Can anyone explain me clearly what is composite number?

Manjot said:   1 decade ago
9 has 3 factors : 9, 3, 1 so it is composite number.

But 11 has not any other factor except 11 and 1.

So it is not a composite number, it is a prime number.

Tell me clearly what is the composite number?

Akhil said:   1 decade ago
Composite no. Means it is divisible by its factor &itsself also or having more than 2 factors.

Its very clear 4, 6, 8, 10, 12, 9 has more than 2 factor but 11 has only 1&11.
