Divisibility Rule of 943
The divisibility rule is a method to determine if a number is divisible by another number without performing actual division. In real life, we can use divisibility rules for quick calculations, dividing things evenly, and sorting items. In this topic, we will discuss the divisibility rule of 943.
What is the Divisibility Rule of 943?
The divisibility rule for 943 is a method to determine if a number is divisible by 943 without performing the division directly. Let's check whether 3772 is divisible by 943 using this rule.
Step 1: Multiply the last digit of the number by 2, in this case, 2 in 3772. So, 2×2=4.
Step 2: Subtract the result from Step 1 from the remaining digits (excluding the last digit). So, 377−4=373.
Step 3: Check if 373 is a multiple of 943. Since 373 is not a multiple of 943, 3772 is not divisible by 943.
Tips and Tricks for Divisibility Rule of 943
Learning the divisibility rule will help students master division. Let's learn a few tips and tricks for the divisibility rule of 943.
Know the multiples of 943:
Memorize the multiples of 943 (943, 1886, 2829, 3772, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 943, then the number is divisible by 943.
Use the negative numbers:
If the result we get after subtraction is negative, disregard the negative sign and consider it 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 not divisible by 943.
For example, check if 9430 is divisible by 943 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, 943−0=943. As 943 is a multiple of 943, 9430 is divisible by 943.
Use the division method to verify:
Students can use the division method to verify and crosscheck their results, which will help them confirm their understanding.
