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 233.
The divisibility rule for 233 is a method by which we can find out if a number is divisible by 233 or not without using the division method. Check whether 466 is divisible by 233 with the divisibility rule.
Step 1: Multiply the last digit of the number by 7 (a key component of 233), here in 466, 6 is the last digit, multiply it by 7. 6 × 7 = 42.
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 46 - 42 = 4.
Step 3: As it is shown that 4 is not a multiple of 233, therefore, the number is not divisible by 233. If the result from step 2 is a multiple of 233, then the number is divisible by 233.
Learn the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 233.
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 233.
For example: Check if 932 is divisible by 233 using the divisibility test.
Multiply the last digit by 7, i.e., 2 × 7 = 14.
Subtract the remaining digits excluding the last digit by 14, 93 - 14 = 79.
Repeat the process: Multiply the last digit of 79 by 7, i.e., 9 × 7 = 63.
Subtract the remaining digits excluding the last digit by 63, 7 - 63 = -56.
As 56 is not a multiple of 233, 932 is not divisible by 233.
Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
