Divisibility Rule of 347

The divisibility rule for 347 is a method by which we can find out if a number is divisible by 347 or not without using the division method. Check whether 1041 is divisible by 347 with the divisibility rule.

Step 1: Multiply the last digit of the number by 2, here in 1041, 1 is the last digit, multiply it by 2. 1 × 2 = 2

Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 104 – 2 = 102.

Step 3: Since 102 is not a multiple of 347, the number is not divisible by 347. If the result from step 2 were a multiple of 347, the number would be divisible by 347.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 347.

Know the multiples of 347:

Memorize the multiples of 347 (347, 694, 1041, 1388, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 347, then the number is divisible by 347.

Use the negative numbers:

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

Repeat the process for large numbers:

Students should keep repeating the divisibility process until they reach a small number that is divisible by 347. For example: Check if 6940 is divisible by 347 using the divisibility test. Multiply the last digit by 2, i.e., 0 × 2 = 0. Subtract the remaining digits excluding the last digit by 0, 694 – 0 = 694. Since 694 is a multiple of 347, 6940 is divisible by 347.

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 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 347 if the result after applying the rule is a multiple of 347.

• Multiples: Multiples are the results we get after multiplying a number by an integer. For example: multiples of 347 are 347, 694, 1041, 1388, etc.

• Integers: Integers are the numbers that include all 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.

• Verification: Using the division method or another method to ensure the correctness of the divisibility test results.
