Which concepts involves finding multiple instances of a number within another number?

The correct answer encompasses all the concepts listed, as they all involve relationships between numbers in distinct ways that can relate to finding instances of one number within another.

Factors refer to numbers that multiply together to equal a particular product. For instance, if you have the number 12, the factors would be pairs like 1 and 12, 2 and 6, or 3 and 4. Each of these factors reveals how many times they can "fit into" the original number when multiplied, which connects to the idea of finding instances of a number.

Multiples, on the other hand, represent the products you get when you multiply a specific number by integers. For example, the multiples of 3 are 3, 6, 9, 12, and so on. Each of these numbers shows how many times 3 can be added together, which again relates to the concept of finding instances of that number within a sequence of numbers.

Divisors are similar to factors in that they also reflect how one number can be divided by another without leaving a remainder. For example, since 10 can be divided by 1, 2, 5, and 10, these numbers are divisors of 10. This
