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 1323, how they are used in real life, and the tips to learn them quickly.
The numbers that divide 1323 evenly are known as factors of 1323.
A factor of 1323 is a number that divides the number without remainder.
The factors of 1323 are 1, 3, 7, 9, 21, 27, 49, 63, 147, 189, 441, and 1323.
Negative factors of 1323: -1, -3, -7, -9, -21, -27, -49, -63, -147, -189, -441, and -1323.
Prime factors of 1323: 3, 7.
Prime factorization of 1323: 3³ × 7².
The sum of factors of 1323: 1 + 3 + 7 + 9 + 21 + 27 + 49 + 63 + 147 + 189 + 441 + 1323 = 2280
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 1323. Identifying the numbers which are multiplied to get the number 1323 is the multiplication method.
Step 1: Multiply 1323 by 1, 1323 × 1 = 1323.
Step 2: Check for other numbers that give 1323 after multiplying:
3 × 441 = 1323
7 × 189 = 1323
9 × 147 = 1323
21 × 63 = 1323
27 × 49 = 1323
Therefore, the positive factor pairs of 1323 are: (1, 1323), (3, 441), (7, 189), (9, 147), (21, 63), and (27, 49).
All these factor pairs result in 1323.
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 1323 by 1, 1323 ÷ 1 = 1323.
Step 2: Continue dividing 1323 by the numbers until the remainder becomes 0.
1323 ÷ 1 = 1323
1323 ÷ 3 = 441
1323 ÷ 7 = 189
1323 ÷ 9 = 147
1323 ÷ 21 = 63
1323 ÷ 27 = 49
Therefore, the factors of 1323 are: 1, 3, 7, 9, 21, 27, 49, 63, 147, 189, 441, 1323.
The factors can be found by dividing them with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 1323 divide the number to break it down in the multiplication form of prime factors until the remainder becomes 1.
1323 ÷ 3 = 441
441 ÷ 3 = 147
147 ÷ 3 = 49
49 ÷ 7 = 7
7 ÷ 7 = 1
The prime factors of 1323 are 3 and 7.
The prime factorization of 1323 is: 3³ × 7².
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1323 is divided by 3 to get 441.
Step 2: Now divide 441 by 3 to get 147.
Step 3: Then divide 147 by 3 to get 49.
Step 4: Divide 49 by 7 to get 7.
Here, 7 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 1323 is: 3³ × 7².
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 1323: (1, 1323), (3, 441), (7, 189), (9, 147), (21, 63), (27, 49).
Negative factor pairs of 1323: (-1, -1323), (-3, -441), (-7, -189), (-9, -147), (-21, -63), (-27, -49).
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 7 teams and 1323 candies. How will they divide them equally?
They will get 189 candies each.
To divide the candies equally, we need to divide the total candies by the number of teams.
1323 ÷ 7 = 189
A garden is rectangular, the length of the garden is 21 meters and the total area is 1323 square meters. Find the width?
63 meters.
To find the width of the garden, we use the formula,
Area = length × width
1323 = 21 × width
To find the value of width, we need to shift 21 to the left side.
1323 ÷ 21 = width
Width = 63.
There are 9 baskets and 1323 apples. How many apples will be in each basket?
Each basket will have 147 apples.
To find the apples in each basket, divide the total apples by the baskets.
1323 ÷ 9 = 147
In a class, there are 1323 students, and 3 groups. How many students are there in each group?
There are 441 students in each group.
Dividing the students by the total groups, we will get the number of students in each group.
1323 ÷ 3 = 441
1323 books need to be arranged in 27 shelves. How many books will go on each shelf?
Each of the shelves has 49 books.
Divide total books by shelves.
1323 ÷ 27 = 49
