Knowing the divisibility rules is important because they provide quick methods for determining whether a number can be divided by another without performing full division. This skill aids in simplifying calculations, making estimations, and solving problems in arithmetic and algebra more efficiently. Additionally, understanding these rules can enhance number sense and facilitate mental math, which is valuable in everyday situations and more complex mathematical concepts.

What are reasons of using the disivility rules?
You can always check on the divisibility of a number by dividing it into another number. But if you know the divisibility rules, you can get that information easier and faster.
How divisibility rules can help you find common factors?
Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.
