Divisibility Rule of 202

The divisibility rule for 202 is a method by which we can find out if a number is divisible by 202 or not without using the division method. Check whether 40404 is divisible by 202 with the divisibility rule.  

Step 1: Look for a pattern or a method specific to 202. Since 202 is 2 × 101, check if the number is divisible by both 2 and 101.

Step 2: Ensure the last digit is even for divisibility by 2. In 40404, the last digit is 4, which is even.

Step 3: For divisibility by 101, separate the number into pairs from the right and add them. If the result is divisible by 101, then the whole number is divisible by 101. 

Example: For 40404, split into pairs: 04 and 040. Add them: 4 + 40 = 44. Since 44 is not divisible by 101, 40404 is not divisible by 202.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 202.

• Know the factors of 202: Recognize that 202 is a product of 2 and 101. Checking divisibility by these factors can help.
   
• Use pairing method: For checking divisibility by 101, use the pairing method as explained to simplify large numbers.
   
• Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a manageable number.
   
• Use the division method to verify: Students can use the division method to verify and crosscheck their results. This will help them to verify and also learn.

• Divisibility rule: A set of guidelines to determine if a number is divisible by another without direct division.
   
• Factors: Numbers that can be multiplied together to obtain a given number (e.g., factors of 202 are 2 and 101).
   
• Pairing method: A technique for checking divisibility by adding pairs of digits.
   
• Multiples: The result of multiplying a number by an integer (e.g., multiples of 101 are 101, 202, 303, etc.).
   
• Even number: A number divisible by 2 without a remainder.
