I use prime numbers in code to catalog things with one number. I assign a Prime number to a certain characteristic. Then I multiply together the prime numbers for each characteristic contained.
Later, that number can be divided a prime number. If a remainder of zero is returned I know it contains the number and what too associate it with.
