Least common multiples to 80 - practice and answers

Distinguish a common multiple from the least positive common multiple. This original three-page pack focuses on least common multiples with inputs up to 80. The first two pages provide twenty-four distinct exercises with blank working space. The third page gives the matching answers, kept separate so it can be removed before practice. One example from this exact pack is "LCM of 67 and 22"; its answer is "1474". Read the task direction before beginning, and use the key to review reasoning rather than guessing from a pattern. No curriculum certification or learning outcome is promised.

Make it work on your printer.

Find the smallest positive number that is a multiple of both given integers. Pages 1 and 2 contain practice A and B; page 3 is the answer key. Print the answer page separately if needed. Equivalent exact answers may be valid even when written differently from the key.

Select the file matching the paper loaded in your printer. Choose portrait orientation and actual size (100%). If your printer clips the edge, use its fit-to-page setting and check the print preview first. Print a single page before making several copies.

For a multipage pack, select the page range you need. Page numbers appear in the lower right of every sheet.
