In order to find the GCF (<em>Greatest Common Factor</em>) of two numbers, list each number's factors. The number of greatest value that shows in both sets is the GCF.
<u>First, list the factors of 5 and 15.</u>
5 - 1, 5
15 - 1, 3, 5, 15
<u>The numbers that show in both sets are 1 and 5. Since 5 is the greatest of the duplicate numbers, </u><u>5 is the GCF.</u>
The store that is larger sells shirts at a better price because they have greater supply in comparison to the demand of shirts. The price is $2.99 because the larger store offers a discount of 10%.
