Divisibility Rule of 313
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 use divisibility rules for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 313.
What is the Divisibility Rule of 313?
The divisibility rule for 313 is a method by which we can determine if a number is divisible by 313 without directly dividing. Check whether 203,569 is divisible by 313 using this rule.
Step 1: Take the last three digits of the number, here in 203,569, which are 569.
Step 2: Subtract 3 times this value from the rest of the number, i.e., 203 - 3 × 569.
Step 3: Calculate 203 - 1707 = -1504.
Step 4: If the result is a multiple of 313, then the original number is divisible by 313. If not, it is not divisible.
Tips and Tricks for Divisibility Rule of 313
Learning the divisibility rule can help students master division. Let’s explore some tips and tricks for the divisibility rule of 313.
Know the multiples of 313:
Memorize the multiples of 313 (313, 626, 939, ...etc.) to quickly check divisibility. If the result from subtraction is a multiple of 313, then the number is divisible by 313.
Use negative numbers:
If the subtraction result is negative, consider its absolute value to check divisibility.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is easily recognizable as a multiple of 313. For example, check if 94,513 is divisible by 313 using the divisibility test. Take the last three digits, which is 513, and calculate 94 - 3 × 513 = 94 - 1539 = -1445. Repeat the process: Take the absolute value, 1445, and do 1 - 3 × 445 = 1 - 1335 = -1334. Since -1334 is not a multiple of 313, 94,513 is not divisible by 313.
Use the division method to verify:
Students can use the division method to verify their results. This will help them confirm their understanding.
Common Mistakes and How to Avoid Them in Divisibility Rule of 313

Mistake 4
Not considering negative values properly.
Use the absolute value of negative results when checking for divisibility.
Mistake 5
Confusing the steps.
Practice regularly to familiarize yourself with the steps.
