Final answer:
To make the least number of gift bags with no items left over, divide the number of candles and bottles of lotion by the smallest common factor of both numbers.
Step-by-step explanation:
To find the least number of gift bags you can make, you need to divide the number of candles and bottles of lotion by the smallest common factor of both numbers. In this case, the smallest common factor of 6 and 8 is 2. If you divide 6 by 2, you get 3, and if you divide 8 by 2, you get 4.
Therefore, you can make 3 gift bags with 2 candles each and 4 bottles of lotion in each bag. No items will be left over.
The correct answer is 3 gift bags.
