Divisibility Rule of 812

Professor Greenline Explaining Math Concepts

The divisibility rule is a method to determine whether a number is divisible by another number without using the division method. In real life, we can use divisibility rules for quick math, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 812.

What is the Divisibility Rule of 812?

The divisibility rule for 812 is a technique to determine if a number is divisible by 812 without performing the division. Check whether 8120 is divisible by 812 using the divisibility rule.

 

Step 1: Divide the number by its factors. For 812, the factors are 2, 4, 101, and 203. Check divisibility by each factor:


8120 ends in 0, so it is divisible by 2.


The last two digits, 20, are divisible by 4.


For 101, sum the digits: 8+1+2+0=11, which is not divisible by 101.


For 203, apply the rule of 203: double the last digit (0×2=0) and subtract it from the rest (812–0=812), which is divisible by 203.

Since 8120 is not divisible by 101, it is not divisible by 812.

Tips and Tricks for Divisibility Rule of 812

Learning the divisibility rule helps kids master division. Here are a few tips and tricks for the divisibility rule of 812.

 

Know the factors of 812:


Memorize the factors of 812 (2, 4, 101, 203) to quickly check divisibility. If a number is divisible by all these factors, it is divisible by 812.

 

Use prime factorization:


812 = 2^2 × 203. If a number is divisible by 2 twice (or by 4) and by 203, it is divisible by 812.

 

Repeat the process for large numbers:


Keep repeating the divisibility test for each factor until you confirm divisibility by 812.

 

Use division method to verify:


Students can use the division method to verify and crosscheck their results, ensuring accuracy.
