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.
