Free worksheets for prime factorization / find factors of a number

Create an unlimited supply of free worksheets for prime factorization or for finding all the factors of the given numbers. The worksheets are available in both html and PDF formats (both are easy to print), and they come with an answer key on the second page of the file.

Each worksheet is randomly generated and thus unique. You can customize the worksheets by choosing the difficulty level, limits for the numbers to be factored, font size, spacing, border, and the number of problems.

The answer key will list the factorization using exponential notation: each prime factor is raised to the appropriate power.

Note: The largest number to be factored allowed is 10,000, because I don't want people to try such enormous factoring feats that it would crash the server. Just to be safe.
