## How To Find Factors of 54 Through Division Method?

We will first use the division method to find the factors of 54. As per this approach, we will multiply 54 with a sequence of natural numbers. The numbers that can divide 54 evenly, without leaving reminders are its factors. The steps below give a detailed account of how to find the factors of 54 using the division method.

• 54 ÷ 1 = 54

• 54 ÷ 2 = 27

• 54 ÷ 3 = 18

• 54 ÷ 18 = 3

• 54 ÷ 27 = 2

• 54 ÷ 54 = 1

We can see that the numbers which do not leave any remainder when divided by 54 are 1, 2, 3, 6, 9, 18, 27, and 54. Thus, they are the factors of 54.

## What Is the Prime Factorization of 54?

Before we use the prime factorization method, we must first check if the given number is a prime/ composite number. If the number is a prime number, it has only two factors: 1 and 54. If not, it has more than two factors.

We know that 54 is the composite number so, it has more than two factors. We can use the prime factorization method to find its factors.

The steps to find prime factors of 54 using prime factorization are below:

**Step 1:** Divide 54 by the smallest prime number that can divide it. That number is 2.

54 ÷ 2 = 27

**Step 2:** Now, divide 27 by the smallest prime number, which is 3.

27 ÷ 3 = 9

**Step 3:** Divide the quotient by 3 repeatedly until you get the number prime number as the quotient.

9 ÷ 3 = 3

**Step 4:** Now we got 3 as the quotient. Dividing 3 with 3 gives us 1.

3 ÷ 3 = 1

The quotient is 1. Since 1 cannot be divided further, the prime factors of 54 are 3 X 3 X 3 X 2 or 3^{3} X 2. We can also write it down as 2 and 3, as both of them are prime numbers.

## What is the Factor Tree of 54?

Let’s now use the factor tree method to find the factors of 54. As per this method, we will place 54 on top of the factor tree. We will branch it out with one of its pair factors. These pair factors are separated until all branches of the factor tree contain prime numbers.

**Step 1:** Let’s place the number 54 at the top of the factor tree. We will now branch it out into one of its pair factors- 2 and 27.

**Step 2:** Since 2 is a prime number, we can no longer separate it. We will now divide 27 into 3 and 9.

**Step 3:** As we can see, 3 is a prime number but 9 is not, so we will split 9 into 3 and 3.

**Step 4:** We can see that 2 and 3 are both prime numbers. The branches in the factor tree will now be all the prime numbers.

Hence, circling all the branches, 3 X 3 X 3 X 2 or 3^{3} X 2 = 54, which are 54 prime factors.

Below is an image representation of the factor tree of 54, choosing 3 and 27 as pair factors of 54.

## Factors of 54 Pattern

The pattern that we observe from the factors of 54 is explained below:

Factors of 54 = 1, 2, 3, 6, 9, 18, 27, and 54

From the above, it is clear that every second number is double the first. Let’s write them in pairs to simplify it.

(1, 2); (3, 6); (9, 18) and (27, 54)
