Question

define composite number​

Answer 1

A composite number is a positive integer which is not prime (i.e., which has factors other than 1 and itself).

Answer 2

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.[1][2]Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit.
