Example 1: Identifying a Multiple of 8
Problem: Determine if 192 is a multiple of 8.
Solution: To check if 192 is a multiple of 8, we can use the divisibility rule for 8: a number is a multiple of 8 if the last three digits are divisible by 8. Since 192 has only three digits, we use the whole number.
- Divide 192 by 8: 192÷8 = 24
- Since 24 is an integer, 192 is a multiple of 8.
Yes, 192 is a multiple of 8.
Large values are often easier to understand when expressed in scientific notation. You can simplify very large calculations using the Scientific Notation Calculator & Converter.
Example 2: Finding the 15th Multiple of 8
Problem: Find the 15th multiple of 8.
Solution: To find the 15th multiple of 8, multiply 8 by 15.
- Calculation: 8×15 = 120
The 15th multiple of 8 is 120.
If you’re studying related number properties, the Prime Number Checker can help determine whether a number is prime or composite before exploring its factors and multiples.
Example 3: Real-World Application
Problem: A factory packs 8 bottles in each box. How many boxes are needed to pack 1,024 bottles?
Solution: To find out how many boxes are needed, divide the total number of bottles by the number of bottles per box.
- Calculation: 1,024÷8 = 128
The factory needs 128 boxes to pack 1,024 bottles.
Packing and grouping problems often involve percentages when calculating inventory or stock changes. The Percentage Calculator can simplify those calculations.
Practical Examples of Multiples of 8
Example 1: Packing in Bulk
Scenario: A warehouse needs to pack toys into boxes. Each box can hold 8 toys. How many boxes are needed to pack 200 toys?
Solution: To determine the number of boxes required, divide the total number of toys by the capacity of one box.
- Calculation: 200÷8 = 25
25 boxes are needed to pack 200 toys.
Comparing quantities in equal groups becomes easier with the Unit Rate Calculator, especially when solving real-world measurement and comparison problems.
Example 2: Event Seating Arrangement
Scenario: An event planner is arranging seats for a conference. Each row must have 8 chairs. If there are 320 attendees, how many rows of chairs are needed?
Solution: To find the number of rows needed, divide the total number of attendees by the number of chairs per row.
- Calculation: 320÷8 = 40
40 rows of chairs are needed for 320 attendees.
Similar arrangement problems frequently require measuring values and numerical relationships. The Distance Calculator is another useful tool for solving practical mathematical calculations.
Example 3: Budgeting for Supplies
Scenario: A school needs to buy notebooks for students. Notebooks come in packs of 8. If the school needs 1,200 notebooks, how many packs should they purchase?
Solution: To determine the number of packs required, divide the total number of notebooks by the number of notebooks per pack.
- Calculation: 1,200÷8 = 150
The school should purchase 150 packs of notebooks.

FAQs
A multiple of 8 is a number that can be expressed as 8 times an integer. In other words, it is the product of 8 and any whole number (positive, negative, or zero). For example, 8, 16, and 24 are multiples of 8.
To determine if a number is a multiple of 8, check if the last three digits of the number form a number that is divisible by 8. Alternatively, you can divide the number by 8 and see if the result is an integer. If it is, the number is a multiple of 8.
The first ten multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80
Yes, all multiples of 8 are also multiples of 4. This is because 8 is itself a multiple of 4 (8 = 4 × 2). Therefore, any number that is a multiple of 8 can also be expressed as a multiple of 4.
Multiples of 8 can be used in various real-life scenarios such as packaging, event planning, and budgeting. For instance, if items are packed in groups of 8, knowing multiples of 8 helps determine the number of packages needed for a given quantity of items.
Yes, zero is considered a multiple of 8 because any number multiplied by zero is zero. Therefore, 8 × 0 = 0, making zero a multiple of 8.
Yes, negative numbers can be multiples of 8. For example, -8, -16, and -24 are multiples of 8 because they can be expressed as 8 multiplied by a negative integer (e.g., 8 × -1 = -8).
