Factors of 287
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 287, how they are used in real life, and tips to learn them quickly.
What are the Factors of 287?
The numbers that divide 287 evenly are known as factors of 287.
A factor of 287 is a number that divides the number without a remainder.
The factors of 287 are 1, 7, 41, and 287.
Negative factors of 287: -1, -7, -41, and -287.
Prime factors of 287: 7 and 41.
Prime factorization of 287: 7 × 41.
The sum of factors of 287: 1 + 7 + 41 + 287 = 336
How to Find Factors of 287?
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 287. Identifying the numbers which are multiplied to get the number 287 is the multiplication method.
Step 1: Multiply 287 by 1, 287 × 1 = 287.
Step 2: Check for other numbers that give 287 after multiplying: 7 × 41 = 287
Therefore, the positive factor pairs of 287 are: (1, 287) and (7, 41).
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 287 by 1, 287 ÷ 1 = 287.
Step 2: Continue dividing 287 by the numbers until the remainder becomes 0.
287 ÷ 1 = 287
287 ÷ 7 = 41
287 ÷ 41 = 7
Therefore, the factors of 287 are: 1, 7, 41, 287.
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 287 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.
287 ÷ 7 = 41
41 ÷ 41 = 1
The prime factors of 287 are 7 and 41.
The prime factorization of 287 is: 7 × 41.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 287 is divided by 7 to get 41.
Step 2: Now divide 41 by 41 to get 1. Since 41 is a prime number, it cannot be divided further. So, the prime factorization of 287 is: 7 × 41.
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 287: (1, 287) and (7, 41).
Negative factor pairs of 287: (-1, -287) and (-7, -41).
Common Mistakes and How to Avoid Them in Factors of 287
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 287, 1 and 287 are also factors.
Factors of 287 Examples
Problem 1
There are 7 teams and 287 points. How will they distribute it equally?
They will get 41 points each.
Explanation
To divide the points equally, we need to divide the total points with the number of teams.
287/7 = 41
Problem 2
An artwork is rectangular, the length of the artwork is 41 centimeters, and the total area is 287 square centimeters. Find the width?
7 centimeters.
Explanation
To find the width of the artwork, we use the formula,
Area = length × width
287 = 41 × width
To find the value of width, we need to shift 41 to the left side.
287/41 = width
Width = 7.
Problem 3
There are 41 baskets and 287 apples. How many apples will be in each basket?
Each basket will have 7 apples.
Explanation
To find the apples in each basket, divide the total apples with the baskets.
287/41 = 7
Problem 4
In a class, there are 287 students, and 7 groups. How many students are there in each group?
There are 41 students in each group.
Explanation
Dividing the students with the total groups, we will get the number of students in each group.
287/7 = 41
Problem 5
287 books need to be arranged in 41 shelves. How many books will go on each shelf?
Each of the shelves has 7 books.
Explanation
Divide total books with shelves.
287/41 = 7
