Factors of -48
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 -48, how they are used in real life, and tips to learn them quickly.
What are the Factors of -48?
The numbers that divide -48 evenly are known as factors of -48.
A factor of -48 is a number that divides the number without remainder.
The positive factors of -48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
Negative factors of -48: -1, -2, -3, -4, -6, -8, -12, -16, -24, and -48.
Prime factors of -48: 2 and 3.
Prime factorization of -48: -1 × 24 × 3.
The sum of the positive factors of 48: 1 + 2 + 3 + 4 + 6 + 8 + 12 + 16 + 24 + 48 = 124
How to Find Factors of -48?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using the division method
- Prime factors and prime factorization
Finding Factors Using Multiplication
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give -48. Identifying the numbers which are multiplied to get the number -48 is the multiplication method.
Step 1: Multiply -48 by -1, -48 × -1 = 48.
Step 2: Check for other numbers that give 48 after multiplying 2 × -24 = -48
3 × -16 = -48
4 × -12 = -48
6 × -8 = -48
Therefore, the positive factor pairs of -48 are: (1, 48), (2, 24), (3, 16), (4, 12), and (6, 8).
For every positive factor, there is a negative factor.
Finding Factors Using Division Method
Dividing the given numbers with the 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 -48 by -1, -48 ÷ -1 = 48.
Step 2: Continue dividing -48 by the numbers until the remainder becomes 0.
-48 ÷ -1 = 48
-48 ÷ -2 = 24
-48 ÷ -3 = 16
-48 ÷ -4 = 12
-48 ÷ -6 = 8
Therefore, the factors of -48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48, and their negative counterparts.
Prime Factors and Prime Factorization
The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:
- Using prime factorization
- Using factor tree
Using Prime Factorization: In this process, prime factors of -48 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.
-48 ÷ -1 = 48
48 ÷ 2 = 24
24 ÷ 2 = 12
12 ÷ 2 = 6
6 ÷ 2 = 3
3 ÷ 3 = 1
The prime factors of -48 are 2 and 3.
The prime factorization of -48 is: -1 × 24 × 3.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, -48 is divided by -1 to get 48.
Step 2: Now divide 48 by 2 to get 24.
Step 3: Then divide 24 by 2 to get 12.
Step 4: Divide 12 by 2 to get 6.
Step 5: Divide 6 by 2 to get 3. Here, 3 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of -48 is: -1 × 24 × 3.
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 -48: (1, 48), (2, 24), (3, 16), (4, 12), and (6, 8).
Negative factor pairs of -48: (-1, -48), (-2, -24), (-3, -16), (-4, -12), and (-6, -8).
Common Mistakes and How to Avoid Them in Factors of -48
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
Mistake 1
Forgetting the number itself and 1 is a factor
Children might forget to add the given number itself and 1 as a factor. The number itself and 1 are the factors for every word. Always remember to include 1 and the number itself.
For example, in factors of -48, 1 and -48 are also factors.
Mistake 2
Missing Negative Factors
We have used only to mention positive factors every time. There are also negative factors, always check whether you have mentioned negative factors.
For example, the factors of -48 consist of -1, -2, -3, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions as factors. Only whole numbers can be a factor.
For example, thinking 1.5 as a factor, because -48/1.5 = -32, and it is not a whole number.
Mistake 4
Confusing Factors With Prime Numbers
Remember that factors can be any whole numbers, not only just primes.
For example, thinking all the factors of -48 are prime numbers.
For example, 2 and 3 are the prime factors of -48, but it has other factors like 4, 12.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking -48 as -1 × 24 × 3 and missing all the key factors.
Factors of -48 Examples
Problem 1
There are 6 friends and -48 apples. How will they divide it equally?
They will get -8 apples each.
Explanation
To divide the apples equally, we need to divide the total apples with the number of friends.
-48/6 = -8
Problem 2
A rectangular plot has a length of 12 meters and a total area of -48 square meters. Find the width?
-4 meters.
Explanation
To find the width of the plot, we use the formula, Area = length × width
-48 = 12 × width
To find the value of width, we need to shift 12 to the left side.
-48/12 = width
Width = -4.
Problem 3
There are 24 boxes and -48 chocolates. How many chocolates will be in each box?
Each box will have -2 chocolates.
Explanation
To find the chocolates in each box, divide the total chocolates with the boxes.
-48/24 = -2
Problem 4
In a class, there are -48 students, and 3 groups. How many students are there in each group?
There are -16 students in each group.
Explanation
Dividing the students with the total groups, we will get the number of students in each group.
-48/3 = -16
Problem 5
-48 books need to be arranged in 4 shelves. How many books will go on each shelf?
Each of the shelves has -12 books.
Explanation
Divide total books with shelves.
-48/4 = -12
