👉 In mathematics, a commonest is a specific number that occurs most frequently in an ordered set of numbers. It is commonly used to compare two or more numbers and select one as the "common" element. For example: - The commonest number among the following three is 5. - The commonest number among the following five is 3. - The commonest number among the following six is 6. The term "commonest" comes from Latin and means "most frequent."
