Factors are numbers that divide evenly into a given number, resulting in whole number quotients. In this article, we will explore the factors of 36 and delve into their significance.

## What are the factors of 36

To determine the factors of 36, we need to find all the numbers that divide 36 without leaving a remainder.

Let’s start finding the factors of 36

- 36 divided by 1 equals 36
- 36 divided by 2 equals 18
- 36 divided by 3 equals 12
- 36 divided by 4 equals 9
- 36 divided by 6 equals 6
- 36 divided by 9 equals 4
- 36 divided by 12 equals 3
- 36 divided by 18 equals 2
- 36 divided by 36 equals 1

Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.

## Factors of 36 in pairs

One interesting property of factors is that they always come in pairs. For example, if the number ‘a’ is a factor of 36, then the result of dividing 36 by ‘a’ will also be a whole number. This means that for every factor ‘a’, there exists a corresponding factor ‘b’ such that a × b = 36. For instance, the pair factors of 36 are (1, 36), (2, 18), (3, 12), (4, 9), and (6, 6). Notice that factor 6 is unique because it is its own pair.

**Pair Factors of 36** are (1, 36), (2, 18), (3, 12), (4, 9), and (6, 6)

Factors are useful in various mathematical operations. One application is simplifying fractions. If we have a fraction like 18/36, we can divide both the numerator and denominator by their greatest common factor, which in this case is 18. By canceling out the common factor, we get the simplified fraction 1/2. This simplification is possible because the factors of 36 help us identify the greatest common factor.

## Prime factors of 36

Factors are also instrumental in finding the prime factorization of a number. Prime factorization is the process of expressing a number as the product of its prime factors. In the case of 36, its prime factorization is 2 × 2 × 3 × 3, which can be written as 2^2 × 3^2. This representation helps us understand the fundamental building blocks of the number and provides a concise form for various calculations and problem-solving.

**Step 1:** Divide 36 by 2 = 18

**Step 2:** Divide 18 by 2 = 9

**Step 3:** Divide 9 by 3 = 3

**Step 4:** Divide 3 by 3 = 1

Prime factors of 36 are 2 × 2 × 3 × 3 or 2^{2} × 3^{2}

Understanding the factors allows us to analyze their divisibility by different numbers. For example, if a number is divisible by 36, it means that it can be evenly divided by 36 without leaving a remainder. Similarly, we can determine divisibility by smaller factors, such as 2, 3, 4, or 9. This knowledge is particularly valuable when working with multiples, fractions, or solving equations involving 36.
