A chef is preparing a major dinner event and needs bell peppers, onions, and tomatoes in mass quantity from the produce outlet she utilizes. The bell peppers are sold in quantities of 3, the onions are sold in quantities of 6, and the tomatoes are sold in quantities of 7. Given the packaging, what is the smallest number of each the chef can order to ensure that she has exactly the same amount of each (not the number of packages, but rather the number of each type of produce)?

Please solve I will give good rating thank you
