Factors of 865
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 865, how they are used in real life, and tips to learn them quickly.
What are the Factors of 865?
The numbers that divide 865 evenly are known as factors of 865.
A factor of 865 is a number that divides the number without a remainder.
The factors of 865 are 1, 5, 173, and 865.
Negative factors of 865: -1, -5, -173, and -865.
Prime factors of 865: 5 and 173.
Prime factorization of 865: 5 × 173.
The sum of factors of 865: 1 + 5 + 173 + 865 = 1044
How to Find Factors of 865?
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 865. Identifying the numbers which are multiplied to get the number 865 is the multiplication method.
Step 1: Multiply 865 by 1, 865 × 1 = 865.
Step 2: Check for other numbers that give 865 after multiplying
5 × 173 = 865
Therefore, the positive factor pairs of 865 are: (1, 865) and (5, 173).
All these factor pairs result in 865.
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 865 by 1, 865 ÷ 1 = 865.
Step 2: Continue dividing 865 by the numbers until the remainder becomes 0.
865 ÷ 1 = 865
865 ÷ 5 = 173
865 ÷ 173 = 5
Therefore, the factors of 865 are: 1, 5, 173, and 865.
Prime Factors and Prime Factorization
The factors can be found by dividing them 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 865 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
865 ÷ 5 = 173
173 ÷ 173 = 1
The prime factors of 865 are 5 and 173.
The prime factorization of 865 is: 5 × 173.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 865 is divided by 5 to get 173.
Step 2: Now divide 173 by 173 to get 1. Here, 173 is a prime number, which cannot be divided anymore. So, the prime factorization of 865 is: 5 × 173.
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 865: (1, 865) and (5, 173).
Negative factor pairs of 865: (-1, -865) and (-5, -173).
Common Mistakes and How to Avoid Them in Factors of 865
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 865, 1 and 865 are also factors.
Factors of 865 Examples
Problem 1
There are 5 friends and 865 marbles. How will they divide them equally?
They will get 173 marbles each.
Explanation
To divide the marbles equally, we need to divide the total marbles by the number of friends.
865/5 = 173
Problem 2
A garden is rectangular, the length of the garden is 5 meters, and the total area is 865 square meters. Find the width.
173 meters.
Explanation
To find the width of the garden, we use the formula: Area = length × width
865 = 5 × width
To find the value of width, we need to shift 5 to the left side.
865/5 = width
Width = 173.
Problem 3
There are 173 bags and 865 candies. How many candies will be in each bag?
Each bag will have 5 candies.
Explanation
To find the candies in each bag, divide the total candies by the bags.
865/173 = 5
Problem 4
In a class, there are 865 students, and 5 groups. How many students are there in each group?
There are 173 students in each group.
Explanation
Dividing the students by the total groups, we will get the number of students in each group.
865/5 = 173
Problem 5
865 books need to be arranged on 5 shelves. How many books will go on each shelf?
Each of the shelves has 173 books.
Explanation
Divide total books by shelves.
865/5 = 173
