Factor vs. Multiple: The Core Distinction
A factor is a number that divides into another number exactly, with no remainder. In contrast, a multiple is the result of multiplying a number by an integer. Essentially, factors are the numbers you multiply to get a number, while multiples are the numbers you get after multiplying.
Section 2: Key Principles
Think of factors as the building blocks or components of a number. For any given number, there is a finite, limited set of factors. Multiples, on the other hand, are the results of scaling a number up through multiplication, like the numbers in a multiplication table. A number has an infinite number of multiples.
Section 3: A Practical Example
Let's use the number 12. The factors of 12 are 1, 2, 3, 4, 6, and 12, because each of these numbers can divide 12 without leaving a remainder. The multiples of 12 are 12, 24, 36, 48, and so on (12×1, 12×2, 12×3, 12×4...). Notice that factors are smaller than or equal to the number, while multiples (except for the number itself) are larger.
Section 4: Why This Matters
Understanding the difference between factors and multiples is a foundational concept in mathematics. It is crucial for simplifying fractions (using the Greatest Common Factor) and for adding or subtracting fractions with different denominators (using the Least Common Multiple).
