143 is a composite number because it has more than two factors

The product of two prime numbers will be composite.

Composite numbers have more than two factors. So, the numbers which have two or less than two factors are not composite numbers. Numbers which have exactly two factors are prime numbers. 1 is an exceptional case because it is neither prime nor composite since it has only one factor which is 1.

The opposite of prime numbers are composite numbers.
