Multiples of 3
Multiples of 3 are numbers that can be divided evenly by 3. These numbers play a crucial role in various mathematical concepts and have practical applications in everyday life. Understanding multiples of 3 is essential for comprehending fundamental mathematical principles and their real-world implications.
Definition and Properties
A multiple of 3 is a number that results from multiplying 3 by an integer. In other words, it is the product of 3 and any whole number.
- Examples of multiples of 3 include 3, 6, 9, 12, 15, and so on.
- One key property of multiples of 3 is the divisibility rule. A number is divisible by 3 if the sum of its digits is divisible by 3.
Identifying Multiples of 3
The divisibility rule for 3 provides a simple method for identifying multiples of 3. To determine if a number is divisible by 3, add the digits of the number together. If the sum is divisible by 3, then the original number is also divisible by 3.
- For example, the number 123 is divisible by 3 because 1 + 2 + 3 = 6, and 6 is divisible by 3.
- Similarly, the number 456 is not divisible by 3 because 4 + 5 + 6 = 15, and 15 is divisible by 3.
Patterns and Sequences
Multiples of 3 form a distinct pattern and sequence. They increase by 3 each time. This pattern can be represented in a table format.
| Multiple | Value |
