What is composite number.? With example

Dear Student,

A Composite number is any positive integer that has at least one divisor other than 1 and itself...

example : the number 4 is divisible by 1,2 and 4. Therefore 4 has 2 as a divisor other 1 and itself so, 4 is a composite number.
The number 5 is divisible by 1 and 5. Since, it is not having any divisor other 1 and itself, therefore 5 is not a composite number.
