Factors of -47
Factors are the numbers that divide any given number evenly without a 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 -47, how they are used in real life, and tips to learn them quickly.
What are the Factors of -47?
The numbers that divide -47 evenly are known as factors of -47.
A factor of -47 is a number that divides the number without a remainder.
The factors of -47 are -1, 1, -47, and 47.
Prime factors of -47: 47.
The sum of factors of -47: -1 + 1 - 47 + 47 = 0
How to Find Factors of -47?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using division method
- Prime factors and Prime factorization
Finding Factors Using Multiplication
To find factors using multiplication, identify the pairs of numbers that are multiplied to give -47. Identifying the numbers which are multiplied to get the number -47 is the multiplication method.
Step 1: Multiply -47 by 1, -47 × 1 = -47.
Step 2: Check for other numbers that give -47 after multiplying 1 × -47 = -47
Therefore, the positive factor pairs of -47 are: (1, -47).
Finding Factors Using Division Method
Dividing the given numbers with 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 -47 by 1, -47 ÷ 1 = -47.
Step 2: Check if other numbers divide -47 evenly.
-47 ÷ 1 = -47
-47 ÷ -1 = 47
The factors of -47 are: -1, 1, -47, and 47.
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 a factor tree
Using Prime Factorization: Since -47 is a negative number, its prime factorization involves its absolute value, which is 47, a prime number.
The prime factor of -47 is 47.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors.
Since -47 is a prime number (considering its absolute value), the factor tree is simple:
The prime factor of -47 is 47.
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 -47: (1, -47).
Negative factor pairs of -47: (-1, 47).
Common Mistakes and How to Avoid Them in Factors of -47
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 number. Always remember to include 1 and the number itself.
For example, in factors of -47, -1, 1, -47, and 47 are factors.
Mistake 2
Ignoring Negative Factors
We often focus only on positive factors. There are also negative factors, so always check whether you have mentioned negative factors.
For example, the factors of -47 include -1 and -47.
Mistake 3
Including Fractions
Children might sometimes add fractions as factors. Only whole numbers can be a factor.
For example, thinking 0.5 as a factor of -47 because -47/0.5 is not a whole number.
Mistake 4
Confusing Factors With Multiples
Remember that factors are the numbers that divide evenly into the number, not numbers that the number divides into.
For example, thinking of multiples of -47 like -94 as factors.
Mistake 5
Mistake in Prime Factorization
Children might skip steps in factorization and end up writing wrong factors.
For example, not recognizing that 47 is already a prime number.
Factors of -47 Examples
Problem 1
There are -47 apples to distribute among 1 person. How many apples will they get?
They will get -47 apples.
Explanation
To distribute the apples equally, divide the total apples by the number of people.
-47/1 = -47
Problem 2
A debt of -47 dollars is shared among 47 people. How much does each person owe?
Each person owes -1 dollar.
Explanation
To find the debt each person owes, divide the total debt by the number of people.
-47/47 = -1
Problem 3
A temperature drop of -47 degrees is spread over 1 day. What is the average temperature drop per day?
The average temperature drop per day is -47 degrees.
Explanation
To find the average drop per day, divide the total drop by the number of days.
-47/1 = -47
Problem 4
A company loses -47 units of a product over 47 days. What is the average daily loss?
The average daily loss is -1 unit.
Explanation
Dividing the total loss by the total days gives the average daily loss.
-47/47 = -1
Problem 5
A store has a clearance of -47 items over 1 sale. How many items are cleared per sale?
-47 items are cleared per sale.
Explanation
Divide the total items by the number of sales.
-47/1 = -47
