CCSS Math Practice Factors & Multiples . ... Place the following numbers: 3, 5, 6, 10, 12, 15, 17, 25, 30, 33, 35, 36, 40, 42, 55 Multiples of 2 BOTH Multiples of 5 4.OA.4 ... similar to the multiple rule for 3. To determine if a number is a multiple of 9, add the digits. If the sum of the digits is a multiple of 9, the number is a multiple of 9.
Section 1 Finding Factors Factorizing algebraic expressions is a way of turning a sum of terms into a product of smaller ones. The product is a multiplication of the factors. Sometimes it helps to look at a simpler case before venturing into the abstract. The number 48 may be written as a product in a number of di erent ways: 48 = 3 16 = 4 12 ...
When a number written as the product of prime factors, it is called the prime factorization of a number. 48 = 3 * 2 * 2 * 2 * 2 = 3 * 24 To make finding the prime factors easy, you need to be a master of “The Factor Facts” and Divisibility Rules for 2, 3, 5, 7 and 11.
are some rules about divisibility that you can sometimes use to quickly tell if a number is a factor of another number. This can be very helpful when you are testing larger numbers! Using Divisibility Rules

A factor is a number that divides into another number with no remainder. In other words every number is divisible by each of its factors. 1 is a factor of every whole number, because every integer is divisible by one. Examples. 3 and 7 are both factors of 21 because 3 x 7 = 21. 10 and 6 are both factors of 60 because 10 x 6 = 60
