Definition

A factor is a number that divides another number exactly without leaving a remainder.

Description

Factors are numbers that can be multiplied together to get another number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. Understanding factors is essential for simplifying fractions, finding greatest common divisors, and solving algebraic expressions. Factors are used in various real-world applications, such as in engineering to determine dimensions and in finance to calculate interest rates. Teaching students about factors helps them develop a strong foundation in number theory and enhances their problem-solving skills.

Teacher script: "Factors are like building blocks. If you want to build the number 12, you can use blocks of 1, 2, 3, 4, 6, and 12. These are the factors of 12."
