🔢 Understanding Multiples
A multiple is the result of multiplying a number by an integer. For example, the multiples of 3 are 3, 6, 9, 12, 15, etc. Multiples are fundamental to multiplication, division, and many areas of mathematics and real-world applications.
📐 What Are Multiples?
🔢 Definition
A multiple of a number n is any number that can be expressed as n × k, where k is an integer. Multiples are the results of multiplying n by 1, 2, 3, 4, etc.
📊 Sequence Pattern
Multiples form arithmetic sequences where each term increases by the base number. For 4: 4, 8, 12, 16, 20... (each increases by 4)
✅ Divisibility
All multiples of n are divisible by n. For example, all multiples of 5 end in 0 or 5. This property is fundamental to division and remainders.
🧮 Multiplication Table Examples
| Number | First 5 Multiples | Pattern |
|---|---|---|
| 2 | 2, 4, 6, 8, 10 | Even numbers |
| 3 | 3, 6, 9, 12, 15 | Sum of digits divisible by 3 |
| 4 | 4, 8, 12, 16, 20 | Ends with even number |
| 5 | 5, 10, 15, 20, 25 | Ends with 0 or 5 |
| 6 | 6, 12, 18, 24, 30 | Even and sum of digits divisible by 3 |
| 7 | 7, 14, 21, 28, 35 | No special pattern |
| 8 | 8, 16, 24, 32, 40 | Even numbers |
| 9 | 9, 18, 27, 36, 45 | Sum of digits divisible by 9 |
| 10 | 10, 20, 30, 40, 50 | Ends with 0 |
🔗 Relationship to Factors
📈 Factors vs Multiples
Factors divide the number (e.g., factors of 12: 1, 2, 3, 4, 6, 12)
Multiples are divided by the number (e.g., multiples of 3: 3, 6, 9, 12, 15...)
Factors are finite, multiples are infinite
🎯 Common Ground
Every number is both a factor and a multiple of itself
1 is a factor of every number
0 is a multiple of every number
The number itself appears in both lists
🔄 Inverse Relationship
If a is a factor of b, then b is a multiple of a
If b is a multiple of a, then a is a factor of b
This relationship is fundamental to division
Understanding this helps with fractions and ratios
