Divisibility Rule of 201

The divisibility rule for 201 is a method by which we can find out if a number is divisible by 201 or not without using the division method. Check whether 402 is divisible by 201 with the divisibility rule.

Step 1: Add all the digits of the number, here in 402, the sum of the digits is 4 + 0 + 2 = 6.

Step 2: Multiply the result from Step 1 by 67 (as 201 divided by 3 equals 67). 6 × 67 = 402.

Step 3: As it is shown that the original number 402 equals the result from Step 2, the number is divisible by 201. If the result from Step 2 isn't equal to the original number, then it isn't divisible by 201.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 201.

• Know the multiples of 201: Memorize the multiples of 201 (201, 402, 603, 804…etc.) to quickly check divisibility. If the result is equal to the original number, then it is divisible by 201.
   
• Use approximation: If the result from the multiplication is close but not exact, consider it carefully, as rounding errors might indicate near divisibility.
   
• Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a scenario where the multiplication result equals the original number.
   
• 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 2 if it ends with an even number.
   
• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 201 are 201, 402, 603, etc.
   
• Approximation: Estimating a number close to its actual value, which can be useful when checking divisibility.
   
• Integers: Integers are numbers that include all whole numbers, negative numbers, and zero.
   
• Sum of digits: The result of adding all individual digits in a number, used in various divisibility rules.
