Question

each of the composite number has already three factors. justify this statement with an example.​

Answer 1

Every composite number has atleast three factors.

The factors are 1, the number itself and another number.

A number is a prime number if its factors are 1 and the number itself.

So composite numbers have to have a third factor.

eg- 9

Factors of 9 - 1,3,9

Here, 1 and the number itself(9) are already factors. 3 is the external factor which makes 9 a composite number.
