To use Factorize, determine the factors of the randomly selected number. Enter the factorizations in the text box, and click the "Enter" button. (Factorization means the two factors that produce the product in question. Use an asterisk in place of a multiplication sign.) Click "Hint" to see how many factorizations are left. When the you have found all the factors for the number, select a factorization by clicking on it. Click and drag the pointer over the grid to build the factorization you selected. Click the "Check" button to see if the array is correct.
