Finding the factors of a number is discovering which numbers exactly divide the given number with no remainder. Factors are important building blocks in math because they help simplify complex problems, especially in prealgebra.

When we talk about 'factors of numbers,' we mean the whole numbers that, when multiplied together, result in the original number. For instance:
- The factors of 6 are 1, 2, 3, and 6, because they divide 6 without leaving a remainder and result in integer values as 1 * 6 = 6 and 2 * 3 = 6.

Similarly, for the number 200:
- The factors are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200, since all these numbers divide evenly into 200.

When finding factors, it's helpful to use multiplication pairs. These pairs consist of two numbers that multiply together to equal the target number.
The pairs provide a systematic way to identify all possible factors, ensuring no factor is missed out.

For example, in finding factors of 200, the multiplication pairs would be:
- 1 * 200
- 2 * 100
- 4 * 50
- 5 * 40
- 8 * 25
- 10 * 20

By identifying these pairs, you can list down all the unique factors involved. This methodology streamlines the process and makes it easier to verify the accuracy of your factors.

Prealgebra acts as the foundation for higher-level mathematics. It involves understanding basic mathematical concepts like factors, multiplication, and division.
Mastering these basic skills is essential for progressing into algebra and beyond.

When working on factors in prealgebra, breaking down a number into its prime factors often helps. For 200:
- Prime factorization involves dividing 200 by its smallest prime, which is 2, giving us 100.
- Continue dividing 100 by 2 until you cannot: 2 * 2 * 50 = 200.
- Further break down 50 into primes: 2 * 2 * 5 * 5 = 200.

Understanding and using factors and prime factorization makes it easier to solve more complicated equations in your future math studies.
