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 486, how they are used in real life, and tips to learn them quickly.
The numbers that divide 486 evenly are known as factors of 486.
A factor of 486 is a number that divides the number without a remainder.
The factors of 486 are 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, and 486.
Negative factors of 486: -1, -2, -3, -6, -9, -18, -27, -54, -81, -162, -243, and -486
Prime factors of 486: 2 and 3.
Prime factorization of 486: 2 × 35.
The sum of factors of 486: 1 + 2 + 3 + 6 + 9 + 18 + 27 + 54 + 81 + 162 + 243 + 486 = 1092
Factors can be found using different methods. Mentioned below are some commonly used methods:
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 486. Identifying the numbers which are multiplied to get the number 486 is the multiplication method.
Step 1: Multiply 486 by 1, 486 × 1 = 486.
Step 2: Check for other numbers that give 486 after multiplying:
2 × 243 = 486
3 × 162 = 486
6 × 81 = 486
9 × 54 = 486
18 × 27 = 486
Therefore, the positive factor pairs of 486 are: (1, 486), (2, 243), (3, 162), (6, 81), (9, 54), (18, 27).
For every positive factor, there is a negative factor.
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 486 by 1, 486 ÷ 1 = 486.
Step 2: Continue dividing 486 by the numbers until the remainder becomes 0.
486 ÷ 1 = 486
486 ÷ 2 = 243
486 ÷ 3 = 162
486 ÷ 6 = 81
486 ÷ 9 = 54
486 ÷ 18 = 27
Therefore, the factors of 486 are: 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486.
The factors can be found by dividing with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 486 divide the number to break it down into the multiplication form of prime factors until the remainder becomes 1.
486 ÷ 2 = 243
243 ÷ 3 = 81
81 ÷ 3 = 27
27 ÷ 3 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
The prime factors of 486 are 2 and 3.
The prime factorization of 486 is: 2 × 35.
The factor tree is the graphical representation of breaking down any number into prime factors. The following steps show the process:
Step 1: Firstly, 486 is divided by 2 to get 243.
Step 2: Now divide 243 by 3 to get 81.
Step 3: Then divide 81 by 3 to get 27.
Step 4: Divide 27 by 3 to get 9.
Step 5: Divide 9 by 3 to get 3.
Here, 3 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 486 is: 2 × 35.
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 486: (1, 486), (2, 243), (3, 162), (6, 81), (9, 54), (18, 27).
Negative factor pairs of 486: (-1, -486), (-2, -243), (-3, -162), (-6, -81), (-9, -54), (-18, -27).
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
There are 9 bags and 486 apples. How will they distribute them equally?
They will get 54 apples each.
To distribute the apples equally, we need to divide the total apples by the number of bags.
486/9 = 54
A garden is rectangular, the length of the garden is 18 meters and the total area is 486 square meters. Find the width?
27 meters.
To find the width of the garden, we use the formula,
Area = length × width
486 = 18 × width
To find the value of the width, we need to shift 18 to the left side.
486/18 = width
Width = 27.
There are 81 students and 486 pencils. How many pencils will each student get?
Each student will get 6 pencils.
To find the pencils for each student, divide the total pencils by the number of students.
486/81 = 6
In a workshop, there are 486 chairs and 54 rows. How many chairs are there in each row?
There are 9 chairs in each row.
Dividing the chairs by the total rows, we will get the number of chairs in each row.
486/54 = 9
486 books need to be arranged in 27 shelves. How many books will go on each shelf?
Each shelf will have 18 books.
Divide total books by shelves.
486/27 = 18
