Divisibility Rule of 722
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 722.
What is the Divisibility Rule of 722?
The divisibility rule for 722 is a method by which we can find out if a number is divisible by 722 or not without using the division method. Check whether 1444 is divisible by 722 with the divisibility rule.
Step 1: Divide the number into two parts, such that the right part has three digits (or fewer if the number has less than four digits). Here in 1444, the right part is 444, and the left part is 1.
Step 2: Check if both parts are divisible by 722. Since 444 is less than 722, it's not divisible by 722. Therefore, 1444 is not divisible by 722.
Tips and Tricks for Divisibility Rule of 722
Learning the divisibility rule will help kids to master the division. Let’s learn a few tips and tricks for the divisibility rule of 722.
- Know the multiples of 722: Memorize the multiples of 722 (722, 1444, 2166, etc.) to quickly check the divisibility. If a number matches one of these, it is divisible by 722.
- Use estimation: If a number is slightly more than a multiple of 722, it might not be divisible. Quick estimation can help identify such numbers.
- Break down large numbers: For larger numbers, divide them into smaller parts, check each part’s divisibility by 722, and then combine the results.
- Verify with division: 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.
Common Mistakes and How to Avoid Them in Divisibility Rule of 722
