Reteach: FactorsMultiples are skipcounting numbers, or “count by” numbers. To find the multiples of five, we count by 5s. To find the multiples of ten, we count by 10s. To find the multiples of twelve, we count by 12s, and so on.

The various resources listed below are aligned to the same standard, (4OA04) taken from the CCSM (Common Core Standards For Mathematics) as the Factors and multiples Worksheet shown above.
Find all factor pairs for a whole number in the range 1 to 100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1 to 100 is a multiple of a given onedigit number. Determine whether a given whole number in the range 1 to 100 is prime or composite.
