Composite numbers are those numbers greater than 1, that have more than 2 factors. Your question is too ambiguous!
I don't completely agree with the words above. Composite numbers are all numbers that are not prime numbers. In other words, composite numbers are divisible by other numbers besides themselves and 1.
To find the number of factors in a composite number, put the number into prime factored form. For example, the number 24 in prime factored form is 2^3 X 3^1. To find the number of factors of 24, add the number 1 to each of the exponents and multiply their sums. The exponent of 2 is 3, and the exponent of 3 is 1, so (3+1)(1+1) = 4 X 2 = 8. There are eight factors of 24. They are: 1,2,3,4,6,8,12,24.
Here's my question: does anyone know the name or concept behind this algorithm, including more like them?
Thanks.

What is a Number that has many factors?
A number that has more than two factors is a composite number whereas a number that has only two factors is a prime number.
Is 999 a prime or composite number?
999 is a composite number. This is because composite numbers are any number that has more than two factors (one and itself). Therefore, since there are many factors of 999 besides one and itself such as 3, 9, and 27, that makes it a composite number.
What is an example of a composite number?
12 is a composite number. Its factors are 1, 2, 3, 4, 6, and 12. 4 is also a composite number. Its factors are 1, 2, and 4. Any number that has factors in addition to 1 and itself is a composite number.
Is 8 a composite or prime number?

Is a composite number times a composite number always composite?
Yes. To be composite, the first number has at least 2 prime factors, the second number also has at least prime factors; the product of the two will have at least 4 prime factors, so it must be a composite number.
