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 263.

What is the Divisibility Rule of 263?

The divisibility rule for 263 is a method by which we can find out if a number is divisible by 263 or not without using the division method. Check whether 526 is divisible by 263 with the divisibility rule.  


Step 1: Multiply the last digit of the number by 2, here in 526, 6 is the last digit; multiply it by 2. 6 × 2 = 12 


Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 52–12 = 40.


Step 3: Since 40 is not a multiple of 263, the number is not divisible by 263. If the result from step 2 were a multiple of 263, then the number would be divisible by 263.

Tips and Tricks for the Divisibility Rule of 263

Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 263. 

Know the multiples of 263:  


Memorize the multiples of 263 (263, 526, 789, 1052…etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 263, then the number is divisible by 263.

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.

Repeat the process for large numbers:  


Students should keep repeating the divisibility process until they reach a small number that is divisible by 263.  
For example: Check if 1326 is divisible by 263 using the divisibility test.  
Multiply the last digit by 2, i.e., 6 × 2 = 12.  
Subtract the remaining digits excluding the last digit by 12, 132–12 = 120.  
Since 120 is not a multiple of 263, 1326 is not divisible by 263.

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.
