Scissors come in packages of 3. Glue sticks come in packages of 10. Martha wants to buy the same number of each. What is the fewest glue sticks Martha can buy?

Verified Answer :

Martha can buy 30 of each.

If we find the LCM (Least Common Multiple) of each number, it would look something like this:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
10: 10, 20, 30

The LCM would be 30.
