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 363.

What is the Divisibility Rule of 363?

The divisibility rule for 363 is a method by which we can find out if a number is divisible by 363 or not without using the division method. Check whether 2178 is divisible by 363 using the divisibility rule.
 

Step 1: Multiply the last digit of the number by 2, here in 2178, 8 is the last digit, multiply it by 2. 8 × 2 = 16.
 

Step 2: Subtract the result from Step 1 from the remaining digits but do not include the last digit. i.e., 217–16 = 201.
 

Step 3: As it is shown that 201 is not a multiple of 363, therefore, the number is not divisible by 363. If the result from Step 2 is a multiple of 363, then the number is divisible by 363.
 

Tips and Tricks for Divisibility Rule of 363

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 363.

  • Know the multiples of 363: Memorize the multiples of 363 to quickly check divisibility. If the result from the subtraction is a multiple of 363, then the number is divisible by 363.
     
  • Use 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 363.

    For example, check if 4368 is divisible by 363 using the divisibility test. Multiply the last digit by 2, i.e., 8 × 2 = 16.

    Subtract the remaining digits excluding the last digit by 16, 436–16 = 420. Still, 420 is a large number, hence we will repeat the process again and multiply the last digit by 2, 0 × 2 = 0.

    Now subtracting 0 from the remaining numbers excluding the last digit, 42–0 = 42. As 42 is not a multiple of 363, 4368 is not divisible by 363.

  • 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.
