Factors of 139
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 139, how they are used in real life, and tips to learn them quickly.
What are the Factors of 139?
The numbers that divide 139 evenly are known as factors of 139. A factor of 139 is a number that divides the number without a remainder. The factors of 139 are 1 and 139.
Negative factors of 139: -1 and -139.
Prime factors of 139: 139. Since 139 is a prime number, it has no prime factorization other than itself.
The sum of factors of 139: 1 + 139 = 140
How to Find Factors of 139?
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, we need to identify the pairs of numbers that are multiplied to give 139. Identifying the numbers which are multiplied to get the number 139 is the multiplication method. Since 139 is a prime number, the only multiplication that gives 139 is:
Step 1: Multiply 139 by 1, 139 × 1 = 139.
Therefore, the positive factor pair of 139 is: (1, 139). For every positive factor, there is a negative factor.
Finding Factors Using Division Method
Dividing the given number 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 139 by 1, 139 ÷ 1 = 139.
Step 2: Check if 139 can be divided by any other whole number except 139 itself, which it cannot since it is a prime number.
Therefore, the factors of 139 are: 1 and 139.
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, since 139 is a prime number, it cannot be broken down further into other prime factors. The prime factorization of 139 is simply 139.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. However, since 139 is a prime number, it does not break further. So, the prime factorization of 139 is just 139.
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 pair of 139: (1, 139).
- Negative factor pair of 139: (-1, -139).
Common Mistakes and How to Avoid Them in Factors of 139
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 139, 1 and 139 are also factors.
Factors of 139 Examples
Problem 1
There are 139 pages in a book. If it is divided into 1 section, how many pages are in that section?
There will be 139 pages in that section.
Explanation
To divide the pages equally, we use the factor of 1. 139/1 = 139
Problem 2
A garden is circular with a circumference of 139 meters. What is the circumference of an identical garden if the radius is halved?
The circumference will be 69.5 meters.
Explanation
If the radius is halved, the circumference is halved as well. 139/2 = 69.5
Problem 3
An artist has 139 paints and wants to create an equal distribution among 1 gallery. How many paints does each gallery receive?
Each gallery will receive 139 paints.
Explanation
To find how many paints each gallery receives, divide the total paints by the number of galleries. 139/1 = 139
Problem 4
There are 139 chairs in a hall, and they need to be divided into 1 row. How many chairs are there in each row?
There are 139 chairs in each row.
Explanation
Dividing the chairs with the total rows, we will get the number of chairs in each row. 139/1 = 139
Problem 5
139 students need to be arranged in 1 group for an event. How many students will be in that group?
There will be 139 students in that group.
Explanation
Divide the total number of students by the number of groups. 139/1 = 139
