### What is the meaning of composite in math?

Composite numbers are numbers which are divisible by another number other than 1 and the number itself. Ex 1: 15 is divisible by 1, 3, 5 and 15. So, 15 is a composite number. Ex 2: 3 is divisible by 1 and 3 only. So, such numbers which are only divisible by 1 and the number itself are known as Prime numbers.
