Divisibility Rule of 162
The divisibility rule is a way to determine whether a number is divisible by another number without performing division. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 162.
What is the Divisibility Rule of 162?
The divisibility rule for 162 is a method by which we can find out if a number is divisible by 162 without using the division method. Let's check whether 2916 is divisible by 162 using the divisibility rule.
Step 1: Check if the number is divisible by 2, 3, and 9. A number is divisible by 162 if it is divisible by 2, 3, and 9.
For divisibility by 2, the last digit of the number should be even. Here, 6 is even.
For divisibility by 3, the sum of the digits should be a multiple of 3. Here, 2 + 9 + 1 + 6 = 18, and 18 is a multiple of 3.
For divisibility by 9, the sum of the digits should be a multiple of 9. Here, 18 is a multiple of 9.
Step 2: Since 2916 satisfies all three conditions, it is divisible by 162.
Tips and Tricks for Divisibility Rule of 162
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 162.
- Know the multiples of 162: Memorize the multiples of 162 (162, 324, 486, 648, etc.) to quickly check divisibility. If the result from the checks is a multiple of 162, then the number is divisible by 162.
- Check divisibility by 2, 3, and 9: Ensure the number meets all three conditions for divisibility by 2, 3, and 9 to confirm divisibility by 162.
- Use the division method to verify: Students can use the division method to verify and cross-check their results. This will help them verify their work and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 162
The divisibility rule of 162 helps us quickly check if a given number is divisible by 162, but common mistakes like calculation errors can lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking all conditions.
Students should ensure they check divisibility by 2, 3, and 9, as all three are necessary for divisibility by 162.
Divisibility Rule of 162 Examples
Problem 1
Is the number of seats in a theater, 648, divisible by 162?
Yes, 648 is divisible by 162.
Explanation
To determine if 648 is divisible by 162, we can apply the divisibility rule:
1) Break down the number into parts that can easily be divided by 162, such as 162 × 4 = 648.
2) Since 648 is the product of 162 and an integer, 4, it is divisible by 162.
Problem 2
A factory produces 1,458 widgets in a day. Can these widgets be packed equally into boxes of 162 each?
Yes, 1,458 is divisible by 162.
Explanation
To check if 1,458 can be divided equally into boxes of 162:
1) Divide 1,458 by 162, which gives 9.
2) Since 1,458 divided by 162 results in a whole number, 9, the widgets can be packed equally.
Problem 3
Is a library's collection of 324 books divisible by 162?
Yes, 324 is divisible by 162.
Explanation
To determine divisibility:
1) Divide 324 by 162, which gives 2.
2) Since the division results in a whole number, 2, 324 is divisible by 162.
Problem 4
A school event has 972 participants. Can they be grouped into teams of 162?
Yes, 972 is divisible by 162.
Explanation
To verify:
1) Divide 972 by 162, which gives 6.
2) The result is a whole number, hence 972 can be divided equally into groups of 162.
Problem 5
A shipment contains 486 items. Can these items be organized into stacks of 162?
No, 486 is not divisible by 162.
Explanation
To check:
1) Divide 486 by 162, which gives approximately 3.
2) Since the result is not a whole number, 486 cannot be divided equally into stacks of 162.
