Factors of 54

Prime Factorization of 54

The factors of the number 54 are the numbers, positive or negative when two different numbers are multiplied together. Let’s consider an example for better understanding.

The factor pairs of the number 11 can be written as (1, 11) and (-1, -11). When you multiply this pair of the negative numbers, it would give you the same result as you multiply the positive numbers. Hence, you can consider both the positive as well as the negative factors of the number 11.

The factor pairs of the number 54 are whole numbers which can either be positive or negative. However, these factors cannot be a decimal number or an integer. For finding the different factors of a number, you can use the prime factorization method.

Prime Factorization Method

The prime factorization of 54 is a method to find out the prime factors of the number 54. Firstly, consider the numbers 1 and 54 as the factors of 54 and then find out the other pairs which are the multiples of 54. This would give you the number 54 when you multiply them all. For understanding, this method in a better manner read about how you can find the factors of 54 in pairs. You can also learn below how to find the factors of the number 54 with the help of the division method.

But before we proceed, here is what you need to know about the properties of the factors.

The factors of any given number are their exact divisors. This means that the number is exactly divisible by its factors.

  1. Each number has two factors, 1 and the number itself.

  2. The factors are always less than or equal to the number.

  3. The greatest positive factor of any positive number is that number itself.

Prime Factors of the Number 54 by the Division Method

Prime factorization of 54 refers to finding the prime factors of the number 54. For finding the prime factors, you need to divide the number with the least possible prime factor. The result of that number is again divided by the least possible prime factor. You need to repeat this procedure till you reach the number 1.

The prime factorization of 54 results into a prime factor tree of the number 54. All the prime numbers which are used for diving in the prime factor tree are called as the prime factors of 54. Take a look at this illustration:

54 ÷ 2 = 27,

27 ÷ 3 = 9,

9 ÷ 3 = 3,

3 ÷ 3 = 1.

The prime numbers which you used for this division are all the prime factors of the number 54. Hence, the prime factors of 54 are:

2, 3, 3, and 3. In short, the prime factors of 54 are 2 and 3.

Factor Pairs of 54

The factor pairs of 54 are all the different types of combinations of two of the factors of the number 54 which you multiply and get 54 as a result.

The process for finding the factor pairs of 54 is very simple.

Firstly, you need to list down all the factors of the number 54.

Then make pairs of different combinations of these factors and it would give you the factor pairs of 54.

The Different Factors of 54 are:

1, 2, 3, 6, 9, 18, 27, 54.

When you make different pair combinations of these factors, it would give you the factor pairs of 54.

Take a look below at all the factor pairs of the number 54. As you notice, all these factor pairs would result in the number 54 when multiplied together.

1 x 54 = 54

2 x 27 = 54

3 x 18 = 54

6 x 9 = 54

9 x 6 = 54

18 x 3 = 54

27 x 2 = 54

54 x 1 = 54

Hence the Pair Factors of 54 are as follows:

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

 The positive pair factors of the number 54 are (1, 54), (2, 27),(3, 18), and (6, 9).

However, the number 54 also has negative factor pairs.

To find the negative pair factors of 54, proceed with the steps below:

-1 × -54 = 54

Hence, (-1, -54) is a pair factor of 54.

-2 × -27 = 54

Hence, (-2, -27) is a pair factor of 54

-3 × -18 = 54

Hence, (-3, -18) is a pair factor of 54

-6 × -9 = 54

Hence, (-6, -9) is a pair factor of 54

Therefore, the negative pair factors of the number 54 are (-1, -54), (-2, -27), (-3, -18) and

(-6, - 9).

FAQ (Frequently Asked Questions)

1. How can you Calculate the Factors of 54?

You can easily calculate the factors of the number 54 by following these steps:

  1. The first step is to note down the number 54.

  2. Then, follow the prime division method by dividing the number 54 with the lowest possible prime number. The first two numbers when multiplied would give you the number 54 as a result.

  3. Take the numbers 2 and 27. When you multiply together, it would give you the number 54.

  4. The number 2 cannot be factorized further, so you can leave it as it is. However, the number 27 is composite and has factors.

            2 x 1 = 2

  1. Continue factorizing 27 further with the least prime number.

            Factorizing 27 would give you

            27: 3 x 3 x 3 x 1

  1. When you multiply all these factors together it would result in the number 54.

  2. Hence you can write the factorization of 54 in the following manner:

            54 = 2 x 3 x 3 x 3 x 1.
