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 931.
The divisibility rule for 931 is a method by which we can find out if a number is divisible by 931 or not without using the division method. Check whether 1862 is divisible by 931 with the divisibility rule.
Step 1: Multiply the last digit of the number by 3, here in 1862, 2 is the last digit, multiply it by 3. 2 × 3 = 6
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit, i.e., 186–6=180.
Step 3: As it is shown that 180 is not a multiple of 931, therefore, the number is not divisible by 931. If the result from step 2 was a multiple of 931, then the number would be divisible by 931.
Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 931.
Memorize the multiples of 931 (931, 1862, 2793, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 931, then the number is divisible by 931.
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.
Students should keep repeating the divisibility process until they reach a small number that is divisible by 931.
For example: Check if 3724 is divisible by 931 using the divisibility test.
Multiply the last digit by 3, i.e., 4 × 3 = 12.
Subtract the remaining digits excluding the last digit by 12, 372–12=360.
Since 360 is still a large number, repeat the process: Multiply the last digit by 3, 0 × 3=0.
Subtract 0 from the remaining numbers excluding the last digit, 36–0=36.
As 36 is not a multiple of 931, 3724 is not divisible by 931.
Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
