A composite number is a positive integer that has at least one positive divisor other than one or the number itself. Curiously enough, it is possible to arrange all the composite numbers in a table with a single swoop and not by a step-by-step process. 1 is neither a prime number nor a compostie number. So it will be easier to count the prime numbers and subtract them. A composite number n is a positive integer n>1 which is not prime (i.e., it can be divided by whole number other than 1 and itself). What are all composite numbers that are less than 200. A composite number n is a positive integer n>1 which is not prime (i.e., it can be divided by whole number other than 1 and itself). 8 Add a d8 Roll a d8. Combinatorics.

Find factors Run a for loop ranging from 2 to the num entered. All even numbers are divisible by two and so all even numbers greater than two are composite numbers. Sphenic Number - A composite with three distinct prime factors. Highly composite numbers whose number of divisors is also a highly composite number are for n = 1, 2, 6, 12, 60, 360, 1260, 2520, 5040, 55440, 277200, 720720, 3603600, 61261200, 2205403200, 293318625600, 6746328388800, 195643523275200 (sequence A189394 in the OEIS).
