## What Are Factors?

Factors are the building blocks of numbers. Imagine a number as a Lego structure; the factors are the individual Lego pieces that can be multiplied together to build that structure. For example, the factors of 6 are 1, 2, 3, and 6 because 1 × 6 = 2 × 3 = 6. In mathematics, particularly in elementary arithmetic, factors are the key to understanding multiplication, division, and more complex concepts like prime factorization. We will now dive deeper into the factors of 45.

## Definition of Factors of 45

The factors of 45 are the numbers that evenly divide into 45 without any remainder. Think of them as the puzzle pieces that perfectly fit together to create the number 45. These numbers play a vital role in various mathematical concepts and real-world applications. Understanding them provides a strong foundation in math, especially for children.
