What this sheet practices
Students list factors, identify multiples, and find the greatest common factor or least common multiple. Listing systematically — pairs from the outside in — is the habit that prevents missed factors.
Errors worth watching for
- Stopping before reaching the square root and missing the paired factor.
- Confusing factors with multiples.
How to use it
- Set the difficulty. Easy narrows the range; challenge adds missing values or extra steps.
- Choose how many questions and how many fit on a page. Ten per page is the most readable default.
- Print, or save as PDF. Replace any single question with the circular arrow if it does not fit your group.

About this generator
What is the difference between a factor and a multiple?
Factors divide a number evenly; multiples are what you get when you multiply it. 3 is a factor of 12; 12 is a multiple of 3.
How large are the numbers?
Most work stays under 100, which keeps the focus on strategy rather than long lists.
Can I print this worksheet on A4 paper?
Yes. Switch Paper to A4 in the settings panel. The layout recalculates the page height and keeps 0.5-inch margins, so nothing is cut off.
Is an answer key included?
The generator always produces an answer key and worked solutions. They are part of the pass; the student sheet can be previewed and printed for free.
