Factors of 1015
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 1015, how they are used in real life, and the tips to learn them quickly.
What are the Factors of 1015?
The numbers that divide 1015 evenly are known as factors of 1015.
A factor of 1015 is a number that divides the number without remainder.
The factors of 1015 are 1, 5, 7, 29, 35, 145, 203, and 1015.
Negative factors of 1015: -1, -5, -7, -29, -35, -145, -203, and -1015.
Prime factors of 1015: 5, 7, and 29.
Prime factorization of 1015: 5 × 7 × 29.
The sum of factors of 1015: 1 + 5 + 7 + 29 + 35 + 145 + 203 + 1015 = 1440
How to Find Factors of 1015?
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 1015. Identifying the numbers which are multiplied to get the number 1015 is the multiplication method.
Step 1: Multiply 1015 by 1, 1015 × 1 = 1015.
Step 2: Check for other numbers that give 1015 after multiplying
5 × 203 = 1015
7 × 145 = 1015
29 × 35 = 1015
Therefore, the positive factor pairs of 1015 are: (1, 1015), (5, 203), (7, 145), (29, 35).
All these factor pairs result in 1015.
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 1015 by 1, 1015 ÷ 1 = 1015.
Step 2: Continue dividing 1015 by the numbers until the remainder becomes 0.
1015 ÷ 1 = 1015
1015 ÷ 5 = 203
1015 ÷ 7 = 145
1015 ÷ 29 = 35
Therefore, the factors of 1015 are: 1, 5, 7, 29, 35, 145, 203, 1015.
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 1015 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1015 ÷ 5 = 203
203 ÷ 7 = 29
29 ÷ 29 = 1
The prime factors of 1015 are 5, 7, and 29.
The prime factorization of 1015 is: 5 × 7 × 29.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1015 is divided by 5 to get 203.
Step 2: Now divide 203 by 7 to get 29.
Step 3: Divide 29 by 29 to get 1. Here, 29 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1015 is: 5 × 7 × 29.
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 1015: (1, 1015), (5, 203), (7, 145), (29, 35).
Negative factor pairs of 1015: (-1, -1015), (-5, -203), (-7, -145), (-29, -35).
Common Mistakes and How to Avoid Them in Factors of 1015
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 1015, 1 and 1015 are also factors.
Factors of 1015 Examples
Problem 1
There are 5 teams and 1015 points. How will the points be divided equally among the teams?
Each team will get 203 points.
Explanation
To divide the points equally, we need to divide the total points by the number of teams.
1015/5 = 203
Problem 2
A garden is rectangular, the length of the garden is 29 meters and the total area is 1015 square meters. Find the width.
35 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
1015 = 29 × width
To find the value of width, we need to shift 29 to the left side.
1015/29 = width
Width = 35.
Problem 3
There are 7 tables and 1015 chairs. How many chairs will be at each table?
Each table will have 145 chairs.
Explanation
To find the chairs at each table, divide the total chairs by the number of tables.
1015/7 = 145
Problem 4
In a conference, there are 1015 participants, and 29 groups. How many participants are there in each group?
There are 35 participants in each group.
Explanation
Dividing the participants by the total groups, we will get the number of participants in each group.
1015/29 = 35
Problem 5
1015 books need to be arranged in 145 shelves. How many books will go on each shelf?
Each of the shelves has 7 books.
Explanation
Divide total books by shelves.
1015/145 = 7
