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 82.
The divisibility rule for 82 is a method by which we can find out if a number is divisible by 82 or not without using the division method. Check whether 1640 is divisible by 82 with the divisibility rule.
Step 1: Divide the number into two parts, the last two digits and the remaining digits. Here in 1640, the last two digits are 40, and the remaining digits are 16.
Step 2: Multiply the remaining digits by 82, i.e., 16 × 82 = 1312.
Step 3: Add the result from Step 2 to the last two digits. i.e., 1312 + 40 = 1352.
Step 4: Check if 1352 is a multiple of 82. Since 1352 ÷ 82 = 16.5, it is not a whole number, so 1640 is not divisible by 82.
Learning the divisibility rule helps to master division. Let’s learn a few tips and tricks for the divisibility rule of 82.
Know the multiples of 82:
Memorize the multiples of 82 (82, 164, 246, 328, etc.) to quickly check divisibility. If the result from the addition is a multiple of 82, then the number is divisible by 82.
Use the division method to verify:
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 82 helps us quickly check if a given number is divisible by 82, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Is 2460 divisible by 82?
Yes, 2460 is divisible by 82.
To check the divisibility of 2460 by 82, follow these steps:
1) Break the number into smaller groups that add up to 82. Notice that 2460 can be split into 1640 and 820.
2) Check if each number is a multiple of 82. Both 1640 (82 x 20) and 820 (82 x 10) are multiples of 82.
3) Since both parts are divisible by 82, 2460 is divisible by 82.
Check the divisibility rule of 82 for 3276.
No, 3276 is not divisible by 82.
To determine divisibility by 82 for 3276, follow these steps:
1) Break the number into smaller groups that might add up to 82. Use 3280 and subtract 4.
2) Check if 3280 is a multiple of 82. 3280 is 82 x 40, which is a multiple of 82.
3) Subtract 4 from 3280, resulting in 3276, which is not divisible by 82.
Is -492 divisible by 82?
No, -492 is not divisible by 82.
To check if -492 is divisible by 82:
1) Remove the negative sign to focus on 492.
2) Break 492 into parts: 410 and 82.
3) 410 is not a multiple of 82, while 82 is 82 x 1.
4) Since not all parts are divisible by 82, -492 is not divisible by 82.
Can 164 be divisible by 82 following the divisibility rule?
Yes, 164 is divisible by 82.
To determine if 164 is divisible by 82:
1) Break down the number: 164 equals 82 x 2.
2) Since 164 is exactly twice 82, it is divisible by 82.
Check the divisibility rule of 82 for 6724.
Yes, 6724 is divisible by 82.
To check if 6724 is divisible by 82:
1) Break the number into smaller parts: 6724 can be divided into 6560 and 164.
2) 6560 is a multiple of 82 (82 x 80), and 164 is a multiple of 82 (82 x 2).
3) Since both parts are divisible by 82, 6724 is divisible by 82.
