From the table to find the lowest prime factor for 645, look along the top row for 600.Then look down the first column to find 45. Find where this column and line meet andthis is the lowest prime factor, e.g. in this example for 645, 3 is the lowest prime factor. If a P appears in the square then the chosen figure is a prime number, e.g. 919.
