Divisibility Rule of 398

The divisibility rule for 398 is a method by which we can find out if a number is divisible by 398 or not without using the division method. Check whether 796 is divisible by 398 with the divisibility rule.

Step 1: Check the number if it is a multiple of 398. Here, 796 is not an obvious multiple of 398, since 398 × 2 = 796.

Step 2: If the subtraction of any multiple of 398 from 796 results in zero or a multiple of 398, then the number is divisible by 398. Here, 796 - 796 = 0, so 796 is divisible by 398.

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 398.

• Know the multiples of 398: Memorize the multiples of 398 (398, 796, 1194, etc.) to quickly check divisibility. 
   
• Use the subtraction method: If a number is close to a known multiple of 398, subtract the multiple to check for divisibility.
   
• Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is easily checked for divisibility by 398. For example, check if 1592 is divisible by 398 using the divisibility test. 1592 - 1194 = 398, which is a multiple of 398, so 1592 is divisible by 398.
   
• 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.

• Divisibility Rule: The set of rules used to find out whether a number is divisible by another number or not. For example, a number is divisible by 398 if it matches or is a multiple found through subtraction.
   
• Multiples: The results obtained after multiplying a number by an integer. For example, multiples of 398 are 398, 796, 1194, etc.
   
• Subtraction: The process of finding the difference between two numbers, by reducing one number from another.
   
• Integer: Integers are the numbers that include all the whole numbers, negative numbers, and zero.
   
• Verification: The process of confirming the accuracy of a calculation, often using an alternative method like division to ensure correctness.
