Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of -54, how they are used in real life, and tips to learn them quickly.
The numbers that divide -54 evenly are known as factors of -54.
A factor of -54 is a number that divides the number without remainder.
The positive factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.
Negative factors of 54 : -1, -2, -3, -6, -9, -18, -27, and -54.
Prime factors of 54: 2 and 3.
Prime factorization of 54: 2 × 33.
The sum of positive factors of 54: 1 + 2 + 3 + 6 + 9 + 18 + 27 + 54 = 120
Factors can be found using different methods. Mentioned below are some commonly used methods:
To find factors using multiplication, we need to identify the pairs of numbers that multiply to give 54 (ignoring the sign for simplicity). Identifying the numbers which are multiplied to get the number 54 is the multiplication method.
Step 1: Multiply 54 by 1, 54 × 1 = 54.
Step 2: Check for other numbers that give 54 after multiplying:
2 × 27 = 54
3 × 18 = 54
6 × 9 = 54
Therefore, the positive factor pairs of 54 are: (1, 54), (2, 27), (3, 18), and (6, 9).
For every positive factor, there is a negative factor.
Dividing the given number by whole numbers until the remainder becomes zero, and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method
Step 1: Divide 54 by 1, 54 ÷ 1 = 54.
Step 2: Continue dividing 54 by the numbers until the remainder becomes 0.
54 ÷ 1 = 54
54 ÷ 2 = 27
54 ÷ 3 = 18
54 ÷ 6 = 9
Therefore, the factors of -54 are: ±1, ±2, ±3, ±6, ±9, ±18, ±27, ±54.
The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 54 divide the number to break it down into the multiplication form of prime factors until the remainder becomes 1.
54 ÷ 2 = 27
27 ÷ 3 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
The prime factors of 54 are 2 and 3. The prime factorization of 54 is: 2 × 33.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 54 is divided by 2 to get 27.
Step 2: Now divide 27 by 3 to get 9.
Step 3: Then divide 9 by 3 to get 3. Here, 3 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 54 is: 2 × 33.
Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.
Positive factor pairs of 54: (1, 54), (2, 27), (3, 18), and (6, 9).
Negative factor pairs of -54: (-1, -54), (-2, -27), (-3, -18), and (-6, -9).
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
A company has a loss of 54 dollars and wants to distribute it evenly among 6 departments. How much loss will each department bear?
Each department will bear a loss of 9 dollars.
To divide the loss equally, we need to divide the total loss by the number of departments.
54/6 = 9
A garden is rectangular, and the length of the garden is 18 meters while the total area is 54 square meters. Find the width.
3 meters.
To find the width of the garden, we use the formula,
Area = length × width 54 = 18 × width
To find the value of width, we need to shift 18 to the left side.
54/18 = width
Width = 3.
There are 9 crates and -54 apples. How many apples will be in each crate?
Each crate will have -6 apples.
To find the apples in each crate, divide the total apples by the number of crates.
-54/9 = -6
A theater has -54 seats and 3 rows. How many seats are there in each row?
There are -18 seats in each row.
Dividing the seats by the total rows, we will get the number of seats in each row.
-54/3 = -18
A library needs to distribute -54 new books equally on 27 shelves. How many books will go on each shelf?
Each shelf will have -2 books.
Divide total books by shelves.
-54/27 = -2
