About this worksheet
Each worksheet has 20 problems finding the least common multiple of three numbers.
The content limit for this standard allows three numbers at a time, and the site's only other least common multiple worksheet stops at two. Three is not merely more work: with two numbers a student can list multiples of the larger until one divides, and with three that shortcut stops working. The three numbers are never all coprime, since that would make the answer their product and reward multiplying rather than finding multiples. Sheets can be customized, turned into flash cards, or assigned for online learning.
Student objectives
- Find the least common multiple of three numbers.
- Use factors rather than listing multiples.
- Recognize when one number already is the multiple.
Everyday practice
- Find when three repeating events line up.
- Say what the least common multiple of 4, 6 and 8 is.
