The number 10 is classified as a composite number because it has more than two distinct positive divisors. Specifically, the divisors of 10 are 1, 2, 5, and 10 itself. This means that 10 can be divided evenly by these numbers, making it a composite rather than a prime number, which has only two divisors: 1 and itself. In addition to being a composite number, 10 is also significant in various mathematical contexts. It is the base of the decimal system, which is widely used in everyday counting and calculations. The number 10 is often associated with completeness, as it represents a full set of digits from 0 to 9.
