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 -66, how they are used in real life, and tips to learn them quickly.
The numbers that divide -66 evenly are known as factors of -66.
A factor of -66 is a number that divides the number without remainder.
The factors of -66 are 1, 2, 3, 6, 11, 22, 33, and 66.
Negative factors of -66: -1, -2, -3, -6, -11, -22, -33, and -66.
Prime factors of -66: 2, 3, and 11.
Prime factorization of -66: -1 × 2 × 3 × 11.
The sum of factors of 66 (ignoring the negative sign): 1 + 2 + 3 + 6 + 11 + 22 + 33 + 66 = 144
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 -66. Identifying the numbers which are multiplied to get the number -66 is the multiplication method.
Step 1: Multiply -66 by -1, -66 × -1 = 66.
Step 2: Check for other numbers that give -66 after multiplying
-2 × 33 = -66
-3 × 22 = -66
-6 × 11 = -66
Therefore, the positive factor pairs of -66 are: (1, 66), (2, 33), (3, 22), (6, 11).
All these factor pairs result in 66 or -66.
For every positive factor, there is a negative factor.
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 -66 by -1, -66 ÷ -1 = 66.
Step 2: Continue dividing -66 by the numbers until the remainder becomes 0.
-66 ÷ -1 = 66
-66 ÷ -2 = 33
-66 ÷ -3 = 22
-66 ÷ -6 = 11
Therefore, the factors of -66 are: 1, 2, 3, 6, 11, 22, 33, 66.
The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of -66 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
66 ÷ 2 = 33
33 ÷ 3 = 11
11 ÷ 11 = 1
The prime factors of -66 are 2, 3, and 11.
The prime factorization of -66 is: -1 × 2 × 3 × 11.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 66 is divided by 2 to get 33.
Step 2: Now divide 33 by 3 to get 11.
Step 3: Then divide 11 by 11 to get 1. So, the prime factorization of -66 is: -1 × 2 × 3 × 11.
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 -66: (1, 66), (2, 33), (3, 22), (6, 11).
Negative factor pairs of -66: (-1, -66), (-2, -33), (-3, -22), (-6, -11).
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 6 teams and -66 points to be distributed equally. How will they distribute it?
Each team will receive -11 points.
To distribute the points equally, divide the total points by the number of teams.
-66/6 = -11
A rectangular plot has a length of 11 meters and an area of 66 square meters. Find the width?
6 meters.
To find the width of the plot, use the formula, Area = length × width 66 = 11 × width
To find the value of width, divide 66 by 11.
66/11 = width
Width = 6.
There are 3 boxes and -66 items. How many items will be in each box?
Each box will have -22 items.
To find the items in each box, divide the total items by the number of boxes.
-66/3 = -22
In a class, there are -66 candies, and 11 students. How many candies are there for each student?
Each student receives -6 candies.
Dividing the candies by the number of students, we get the number of candies each student receives.
-66/11 = -6
-66 books need to be arranged in 6 shelves. How many books will go on each shelf?
Each shelf will have -11 books.
Divide total books by the number of shelves.
-66/6 = -11
