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 820.
The divisibility rule for 820 is a method by which we can find out if a number is divisible by 820 or not without using the division method. Check whether 1640 is divisible by 820 with the divisibility rule.
Step 1: Check whether the number ends in zero, as 820 is a multiple of 10. Here, 1640 ends in zero.
Step 2: Check if the number divided by 10 (164) is divisible by 82. Since 164 divided by 82 equals 2, it is divisible.
Step 3: As shown, 164 divided by 82 results in an integer, therefore, 1640 is divisible by 820. If the result from step 2 isn't an integer, then the number isn't divisible by 820.
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 820.
Memorize the multiples of 820 (820, 1640, 2460, 3280, etc.) to quickly check divisibility. If the number is a multiple of 820, then it is divisible by 820.
Students can use the division method as a way to verify and cross-check their results. This will help them verify and also learn.
The divisibility rule of 820 helps us to quickly check if the given number is divisible by 820, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you avoid them.
