Divisibility Rule of 322

The divisibility rule for 322 is a method by which we can find out if a number is divisible by 322 or not without using the division method.

Check whether 644 is divisible by 322 with the divisibility rule.  

Step 1: Divide the number into two parts. Here, in 644, split it into 6 and 44.  

Step 2: Check if both parts are divisible by 322. If both parts are divisible or the sum of the parts is divisible by 322, then the number is divisible by 322.  

Step 3: Since 6 and 44 individually are not divisible by 322, we find their sum: 6 + 44 = 50.  

Step 4: Since 50 is not divisible by 322, 644 is not divisible by 322. If the sum or any part is divisible by 322, then the whole number is divisible by 322.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 322.

• Know the multiples of 322: Memorize the multiples of 322 (322, 644, 966, etc.) to quickly check divisibility. If the sum of the parts or any part is a multiple of 322, then the number is divisible by 322.

• Use estimation: If the number is large, estimate by dividing the number into workable parts and checking if they sum up to a multiple of 322.

• Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number or parts that can easily be checked for divisibility by 322.  
  
  For example: Check if 1932 is divisible by 322 using the divisibility test.  
  
  Divide into parts: 19, 32.  
  
  Check if either 19 or 32 is divisible by 322 or their sum.  
  19 + 32 = 51, which is not divisible by 322.  
  
  1932 is not divisible by 322.

• Use the division method to verify: Students can use the division method as a way to verify and crosscheck their results. This will help them verify and also learn.

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not.

• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 322 are 322, 644, 966, etc.

• Integers: Integers are the numbers that include all the whole numbers, negative numbers, and zero.

• Estimation: Estimation is the process of finding an approximate value that is close to the actual value.

• Verification: Verification is the process of checking the accuracy of a calculation or result.
