Assignment: 04-Factors_Multiples_Divisibility
Factors - Numbers that are multiplied together to get a product; could also be defined as numbers that will evenly go into another.
Example: List the factors of 18. 18′s factors are 1, 2, 3, 6, 9, and 18. All of those numbers evenly divide into 18.
Multiples - The easiest way to think of multiples is if you were to count by a certain number.
Example: The multiples of 3 would be listed as if we were counting by 3s: 3, 6, 9, 12, 15, 18, 21, etc….
Divisible - If a number can be evenly divided by another
Example: 14 is divisible by 7 because 7 can go into 14 twice without a remainder.
Certain numbers have rules that will easily tell us if any number is divisible by it. Example, all even numbers are divisible by 2. Here are the rules that we must remember:
