What is a Factor?
In mathematics, a factor refers to a number that divides another number exactly without leaving a remainder. In other words, if you can divide one number by another number and the division result is a whole number, then the second number is a factor of the first number.
Let’s take an example to illustrate this concept. Consider the number 12. Its factors are the numbers that divide 12 without leaving a remainder. In this case, the factors of 12 are 1, 2, 3, 4, 6, and 12. If we divide 12 by any of these numbers, we get a whole number:
- 12 ÷ 1 = 12
- 12 ÷ 2 = 6
- 12 ÷ 3 = 4
- 12 ÷ 4 = 3
- 12 ÷ 6 = 2
- 12 ÷ 12 = 1
These divisions result in whole numbers, indicating that 1, 2, 3, 4, 6, and 12 are all factors of 12. It’s important to note that every number has at least two factors: 1 and itself. These are called trivial factors.
Factors play a significant role in many mathematical concepts and operations. For example, when factoring a number, you find its prime factors, which are the factors that are prime numbers. Prime factors are essential for various mathematical applications such as prime factorization, finding the greatest common divisor (GCD), or simplifying fractions.
Understanding factors helps in solving problems involving divisibility, finding multiples, and working with fractions. Factors also have applications in areas like algebra, number theory, and cryptography.
What are the Factors of 35?
The factors of 35 are the numbers that divide 35 without leaving a remainder. In this case, the factors of 35 are 1, 5, 7, and 35. Let’s explore why these numbers are factors of 35: When we divide 35 by 1, we get 35, which is a whole number.
When we divide 35 by 5, we get 7, which is also a whole number.
When we divide 35 by 7, we again get 5 as the result, which is a whole number.
Finally, when we divide 35 by 35, we get 1, which is a whole number.
Therefore, the factors of 35 are 1, 5, 7, and 35. As mentioned earlier, every number has at least two factors: 1 and itself. In this case, 1 and 35 are the trivial factors of 35.
Understanding the factors of a number is useful in various mathematical applications. For instance, when simplifying fractions, you can find the common factors of the numerator and denominator to reduce the fraction. Factors also help determine whether a number is divisible by another number and are involved in prime factorization, where you express a number as a product of its prime factors.
Factors of -35
The factors of -35 are the numbers that divide -35 without leaving a remainder. In this case, the factors of -35 are -1, -5, -7, and -35. Let’s examine each of these factors in detail:
The number -1 is a factor of -35 because when we divide -35 by -1, we get 35 as the quotient.
The number -5 is a factor of -35 because when we divide -35 by -5, we obtain 7 as the quotient.
The number -7 is a factor of -35 because when we divide -35 by -7, we also get 5 as the quotient.
The number -35 is a factor in itself since dividing -35 by -35 results in 1.
Therefore, the factors of -35 are -1, -5, -7, and -35. Similarly to positive numbers, every negative number has at least two factors: -1 and itself. These factors play a role in various mathematical operations, such as determining divisibility, finding common factors, prime factorization, and simplifying fractions. It’s important to note that when dealing with negative numbers, the signs of the factors alternate to ensure that the division results in a whole number or integer.

Importance of Factor in Math
Factors play a crucial role in various mathematical concepts and applications. Here are some important aspects that highlight the significance of factors in mathematics:
Divisibility: Factors are fundamental in determining the divisibility of numbers. If a number is divisible by another number, it means that the latter number is a factor of the former number. Divisibility rules, such as divisibility by 2, 3, 5, etc., are based on the properties of factors.
Prime Factorization: Prime factorization is the process of expressing a number as a product of its prime factors. It helps in understanding the unique combination of prime numbers that compose a given number. Prime factorization is valuable in various mathematical operations, such as simplifying fractions, finding common factors, and solving equations involving factors.
Common Factors: Finding common factors between two or more numbers is useful in various contexts. It helps identify the shared divisors or factors that can be used to simplify expressions, solve equations, and determine the greatest common divisor (GCD) or lowest common multiple (LCM) of multiple numbers.
Simplification: Factors are employed to simplify fractions. By canceling out common factors in the numerator and denominator, fractions can be simplified to their lowest terms, making them easier to work with in calculations and comparisons.
Factoring Polynomials: In algebra, factoring polynomials is an essential skill. It involves breaking down a polynomial expression into its factors, which allows for easier manipulation, solving equations, and identifying key characteristics of the polynomial.
Number Properties: Factors help uncover properties and characteristics of numbers. For example, if a number has exactly two factors (1 and itself), it is classified as a prime number. On the other hand, numbers with more than two factors are known as composite numbers. Understanding the properties of factors assists in classifying and analyzing numbers.
Problem-Solving: Factors play a role in problem-solving across various mathematical domains. They provide a framework for breaking down complex problems into simpler components, identifying patterns, and finding efficient solutions.
Mathematical Relationships: Factors help establish relationships between numbers. For instance, the product of two factors of a number equals the number itself. This relationship is instrumental in verifying factorizations, checking solutions, and exploring number patterns.
Prime Numbers and Primality Testing: Factors are closely tied to prime numbers. Prime numbers have only two distinct factors: 1 and the number itself. Factors are essential in primality testing, which involves determining whether a given number is prime or composite.
In summary, factors are vital in mathematics as they contribute to divisibility rules, prime factorization, simplification of fractions, factoring polynomials, understanding number properties, solving problems, establishing mathematical relationships, and identifying prime numbers. They provide a foundation for numerous mathematical concepts and their applications across various disciplines.
