Divisibility Rule of 731
The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 731.
What is the Divisibility Rule of 731?
The divisibility rule for 731 is a method by which we can find out if a number is divisible by 731 without using the division method. Here is an example to check whether 2193 is divisible by 731 using the divisibility rule.
Step 1: Multiply the last digit of the number by 2. In 2193, 3 is the last digit, so multiply it by 2. 3 × 2 = 6.
Step 2: Subtract the result from Step 1 from the remaining values without including the last digit. i.e., 219–6 = 213.
Step 3: As 213 is not a multiple of 731, 2193 is not divisible by 731. If the result from Step 2 were a multiple of 731, the number would be divisible by 731.
Tips and Tricks for Divisibility Rule of 731
Learning divisibility rules will help kids master division. Let's learn a few tips and tricks for the divisibility rule of 731.
Know the multiples of 731:
Memorize the multiples of 731 (731, 1462, 2193, ... etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 731, then the number is divisible by 731.
Use negative numbers:
If the result we get after subtraction is negative, we will consider the absolute value for checking divisibility.
Repeat the process for large numbers:
Students should repeat the divisibility process until they reach a smaller number to check divisibility by 731. For example, to check if 4386 is divisible by 731, multiply the last digit by 2, i.e., 6 × 2 = 12. Subtract the remaining digits excluding the last digit by 12, 438–12 = 426. As 426 is not a multiple of 731, 4386 is not divisible by 731.
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.
