Divisibility Rule of 841

The divisibility rule for 841 is a method by which we can find out if a number is divisible by 841 or not without using the division method. Check whether 1682 is divisible by 841 with the divisibility rule.

Step 1: Divide the number into two parts. For 1682, consider the first part as 1 and the second part as 682.

Step 2: Check if the first part, 1, is a multiple of 841. Since it is not, multiply the first part by 10 and add it to the second part: 10×1+682=692.

Step 3: As 692 is not a multiple of 841, repeat the process. Multiply the first part by 10 again and add it to the second part: 10×6+92=152.

Step 4: 152 is a multiple of 841, which means the original number 1682 is divisible by 841.

Learn divisibility rules to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 841.

1. Know the multiples of 841:

Memorize the multiples of 841 to quickly check divisibility. If the result from the addition is a multiple of 841, then the number is divisible by 841.

2. Use the negative numbers:

If the result we get after the process is negative, we will avoid the symbol and consider it as positive for checking divisibility.

3. Repeat the process for large numbers:

Students should keep repeating the divisibility process until they reach a small number that is divisible by 841. For example: Check if 4205 is divisible by 841 using the divisibility test.

Step 1: Divide into parts: 4 and 205.
   
Step 2: Multiply the first part by 10 and add to the second: 10×4+205=245.

Step 3: 245 is a multiple of 841, so 4205 is divisible by 841.

4. 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 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.

• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 841 are 841, 1682, 2523, etc.

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

• Subtraction: Subtraction is a process of finding out the difference between two numbers by reducing one number from another.

• Addition: In this context, addition is used to combine the product of the first part and 10 with the second part to check divisibility.
