The number 9 is an example of a number that is both odd and composite. An odd number is one that is not divisible by 2, and a composite number is one that has more than two positive divisors. In the case of 9, its divisors are 1, 3, and 9, making it composite as well as odd. Other examples include 15, 21, and 25.
120,000 has 70 proper divisors.
