The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 209.

What is the Divisibility Rule of 209?

The divisibility rule for 209 is a method by which we can find out if a number is divisible by 209 or not without using the division method. Check whether 4180 is divisible by 209 with the divisibility rule.  


Step 1: Multiply the last digit of the number by 9, here in 4180, 0 is the last digit; multiply it by 9. 0 × 9 = 0.


Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 418–0 = 418.


Step 3: Divide the result by 11. 418 ÷ 11 = 38.


Step 4: Check if the result from Step 3 is divisible by 19. Since 38 ÷ 19 = 2, 4180 is divisible by 209.


If the result from Step 4 isn't a whole number, then the original number isn't divisible by 209.
 

Tips and Tricks for Divisibility Rule of 209

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 209.

1. Know the steps:

Memorize the steps of the divisibility rule of 209 to quickly check divisibility. This involves multiplication by 9, subtraction, division by 11, and checking divisibility by 19.

2. Use the negative numbers:

If the result we get after the subtraction is negative, we will avoid the symbol and consider it as positive for checking the divisibility of a number.

3. Repeat the process for large numbers:

Students should keep repeating the divisibility process until they reach a small number that is divisible by 209.

4. Use the division method to verify:

Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.
