Factors of 1286
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 1286, how they are used in real life, and tips to learn them quickly.
What are the Factors of 1286?
The numbers that divide 1286 evenly are known as factors of 1286.
A factor of 1286 is a number that divides the number without remainder.
The factors of 1286 are 1, 2, 643, and 1286.
Negative factors of 1286: -1, -2, -643, and -1286.
Prime factors of 1286: 2 and 643.
Prime factorization of 1286: 2 × 643.
The sum of factors of 1286: 1 + 2 + 643 + 1286 = 1932
How to Find Factors of 1286?
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 1286. Identifying the numbers which are multiplied to get the number 1286 is the multiplication method.
Step 1: Multiply 1286 by 1, 1286 × 1 = 1286.
Step 2: Check for other numbers that give 1286 after multiplying:
2 × 643 = 1286
Therefore, the positive factor pairs of 1286 are: (1, 1286) and (2, 643).
All these factor pairs result in 1286.
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 1286 by 1, 1286 ÷ 1 = 1286.
Step 2: Continue dividing 1286 by the numbers until the remainder becomes 0.
1286 ÷ 1 = 1286
1286 ÷ 2 = 643
Therefore, the factors of 1286 are: 1, 2, 643, 1286.
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 1286 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1286 ÷ 2 = 643
643 is a prime number and cannot be divided further.
The prime factors of 1286 are 2 and 643.
The prime factorization of 1286 is: 2 × 643.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1286 is divided by 2 to get 643. 643 is a prime number, so it cannot be divided further.
So, the prime factorization of 1286 is: 2 × 643.
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 1286: (1, 1286) and (2, 643).
Negative factor pairs of 1286: (-1, -1286) and (-2, -643).
Common Mistakes and How to Avoid Them in Factors of 1286
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 1286, 1 and 1286 are also factors.
Factors of 1286 Examples
Problem 1
There are 6 teams and 1286 points. How will they distribute the points equally?
They will distribute approximately 214.33 points each.
(Note: This indicates that 1286 is not evenly divisible by 6.)
Explanation
To divide the points equally, we need to divide the total points by the number of teams.
1286 ÷ 6 = 214.33
Problem 2
A rectangular plot has a width of 2 meters and a total area of 1286 square meters. Find the length.
643 meters.
Explanation
To find the length of the plot, we use the formula,
Area = length × width
1286 = length × 2
To find the value of length, divide the area by the width.
1286 ÷ 2 = length
Length = 643.
Problem 3
There are 1286 apples to be packed in crates. If each crate can hold 643 apples, how many crates are needed?
2 crates are needed.
Explanation
To find the number of crates needed, divide the total apples by the number each crate can hold.
1286 ÷ 643 = 2
Problem 4
A class has 1286 students, and they need to form groups where each group contains 2 students. How many groups can be formed?
643 groups can be formed.
Explanation
Dividing the students by the group size, we will get the number of groups.
1286 ÷ 2 = 643
Problem 5
1286 books need to be arranged on 2 shelves. How many books will go on each shelf?
Each of the shelves will have 643 books.
Explanation
Divide the total books by the number of shelves.
1286 ÷ 2 = 643
