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 312.
The divisibility rule for 312 is a method by which we can find out if a number is divisible by 312 or not without using the division method. Check whether 936 is divisible by 312 with the divisibility rule.
Step 1: Check if the number is divisible by 3. For 936, sum the digits: 9+3+6=18, which is divisible by 3.
Step 2: Check if the number is divisible by 4. The last two digits of 936 are 36, and 36 is divisible by 4.
Step 3: Check if the number is divisible by 13. Divide 936 by 13; 936 ÷ 13 = 72, which is an integer.
Since 936 passes all these conditions, it is divisible by 312.
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 312.
Memorize some multiples of 312 (e.g., 312, 624, 936, etc.) to quickly check divisibility. If a number is a multiple of 312, it is divisible by 312.
For a number to be divisible by 312, it must be divisible by 3, 4, and 13. This makes it easier to check larger numbers.
Students should keep repeating the divisibility process for each sub-rule (3, 4, 13) until they reach a conclusion.
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.
The divisibility rule of 312 helps us quickly check if a given number is divisible by 312, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Is 1248 divisible by 312?
