Factors of -143
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 -143, how they are used in real life, and tips to learn them quickly.
What are the Factors of -143?
The numbers that divide -143 evenly are known as factors of -143.
A factor of -143 is a number that divides the number without remainder.
The factors of -143 are 1, -1, 11, -11, 13, -13, 143, and -143.
Prime factors of -143: 11 and 13.
Prime factorization of 143: 11 × 13.
The sum of factors of 143: 1 + 11 + 13 + 143 = 168
How to Find Factors of -143?
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 143. Identifying the numbers that are multiplied to get the number 143 is the multiplication method.
Step 1: Multiply 143 by 1, 143 × 1 = 143.
Step 2: Check for other numbers that give 143 after multiplying: 11 × 13 = 143
Therefore, the positive factor pairs of 143 are: (1, 143), (11, 13).
All these factor pairs result in 143.
For every positive factor, there is a negative factor.
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 143 by 1, 143 ÷ 1 = 143.
Step 2: Continue dividing 143 by the numbers until the remainder becomes 0.
143 ÷ 1 = 143
143 ÷ 11 = 13
143 ÷ 13 = 11
Therefore, the factors of 143 are: 1, 11, 13, 143.
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 143 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
143 ÷ 11 = 13
13 ÷ 13 = 1
The prime factors of 143 are 11 and 13.
The prime factorization of 143 is: 11 × 13.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 143 is divided by 11 to get 13.
Step 2: Now divide 13 by 13 to get 1. So, the prime factorization of 143 is: 11 × 13. 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 143: (1, 143), (11, 13).
Negative factor pairs of -143: (-1, -143), (-11, -13).
Common Mistakes and How to Avoid Them in Factors of -143
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 143, 1 and 143 are also factors.
Factors of -143 Examples
Problem 1
There are 143 students and they need to form groups of 13. How many groups will be formed?
11 groups will be formed.
Explanation
To divide the students into groups, we need to divide the total students by the group size.
143/13 = 11
Problem 2
A ribbon is 143 meters long and needs to be cut into pieces of 11 meters each. How many pieces will be formed?
13 pieces.
Explanation
To find the number of pieces, we use the division
143 = 11 × number of pieces
143/11 = number of pieces
Number of pieces = 13.
Problem 3
A party has 11 tables, and 143 guests. How many guests will sit at each table?
Each table will have 13 guests.
Explanation
To find the guests at each table, divide the total guests by the number of tables.
143/11 = 13
Problem 4
There are 143 candies and 13 boxes. How many candies will be in each box?
There are 11 candies in each box.
Explanation
Dividing the candies by the total boxes, we will get the number of candies in each box.
143/13 = 11
Problem 5
143 books need to be arranged in 11 shelves. How many books will go on each shelf?
Each of the shelves has 13 books.
Explanation
Divide total books by shelves.
143/11 = 13
