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 308, how they are used in real life, and tips to learn them quickly.
The numbers that divide 308 evenly are known as factors of 308.
A factor of 308 is a number that divides the number without remainder.
The factors of 308 are 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, and 308.
Negative factors of 308: -1, -2, -4, -7, -11, -14, -22, -28, -44, -77, -154, and -308.
Prime factors of 308: 2, 7, and 11.
Prime factorization of 308: 2² × 7 × 11.
The sum of factors of 308: 1 + 2 + 4 + 7 + 11 + 14 + 22 + 28 + 44 + 77 + 154 + 308 = 672
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 308. Identifying the numbers which are multiplied to get the number 308 is the multiplication method.
Step 1: Multiply 308 by 1, 308 × 1 = 308.
Step 2: Check for other numbers that give 308 after multiplying
2 × 154 = 308
4 × 77 = 308
7 × 44 = 308
11 × 28 = 308
14 × 22 = 308
Therefore, the positive factor pairs of 308 are: (1, 308), (2, 154), (4, 77), (7, 44), (11, 28), (14, 22).
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 308 by 1, 308 ÷ 1 = 308.
Step 2: Continue dividing 308 by the numbers until the remainder becomes 0.
308 ÷ 1 = 308
308 ÷ 2 = 154
308 ÷ 4 = 77
308 ÷ 7 = 44
308 ÷ 11 = 28
308 ÷ 14 = 22
Therefore, the factors of 308 are: 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308.
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 308 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
308 ÷ 2 = 154
154 ÷ 2 = 77
77 ÷ 7 = 11
11 ÷ 11 = 1
The prime factors of 308 are 2, 7, and 11.
The prime factorization of 308 is: 2² × 7 × 11.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 308 is divided by 2 to get 154.
Step 2: Now divide 154 by 2 to get 77.
Step 3: Then divide 77 by 7 to get 11. Here, 11 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 308 is: 2² × 7 × 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 308: (1, 308), (2, 154), (4, 77), (7, 44), (11, 28), and (14, 22).
Negative factor pairs of 308: (-1, -308), (-2, -154), (-4, -77), (-7, -44), (-11, -28), and (-14, -22).
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 14 students and 308 pencils. How will they distribute them equally?
They will get 22 pencils each.
To distribute the pencils equally, we need to divide the total pencils by the number of students.
308/14 = 22
A garden is rectangular, the length of the garden is 11 meters and the total area is 308 square meters. Find the width?
28 meters.
To find the width of the garden, we use the formula,
Area = length × width
308 = 11 × width
To find the value of width, we need to shift 11 to the left side.
308/11 = width
Width = 28.
There are 44 boxes, and 308 marbles. How many marbles will be in each box?
Each box will have 7 marbles.
To find the marbles in each box, divide the total marbles by the number of boxes.
308/44 = 7
In a theater, there are 308 seats, and 11 rows. How many seats are there in each row?
There are 28 seats in each row.
Dividing the seats by the total rows, we will get the number of seats in each row.
308/11 = 28
308 books need to be arranged in 14 shelves. How many books will go on each shelf?
Each of the shelves has 22 books.
Divide total books by shelves.
308/14 = 22
