This factors worksheet is great for practicing finding the Least Common Multiple of
number sets. Understanding Least Common Multiples are very important for working with fraction problems. The
problems may be selected from four different number ranges. The easiest keeps the number set not
greater than 30, and the hardest will keep the number sets not greater than 120. This factors
worksheet will generate 10, 15 or 20 Least Common Multiple problems per worksheet, and remember
every time you create a worksheet the problems will change and will not repeat.
