The sum of factors of 1148: 1 + 2 + 4 + 7 + 14 + 28 + 41 + 82 + 164 + 287 + 574 + 1148 = 2352

Factors can be found using different methods. Mentioned below are some commonly used methods:

1. Finding factors using multiplication
2. Finding factors using division method
3. Prime factors and Prime factorization

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 1148. Identifying the numbers which are multiplied to get the number 1148 is the multiplication method.

Step 1: Multiply 1148 by 1, 1148 × 1 = 1148.

Step 2: Check for other numbers that give 1148 after multiplying  

2 × 574 = 1148     

4 × 287 = 1148    

 7 × 164 = 1148     

14 × 82 = 1148     

28 × 41 = 1148

Therefore, the positive factor pairs of 1148 are: (1, 1148), (2, 574), (4, 287), (7, 164), (14, 82), and (28, 41). 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 1148 by 1, 1148 ÷ 1 = 1148.

Step 2: Continue dividing 1148 by the numbers until the remainder becomes 0.

1148 ÷ 1 = 1148

1148 ÷ 2 = 574

1148 ÷ 4 = 287

1148 ÷ 7 = 164

1148 ÷ 14 = 82

1148 ÷ 28 = 41

Therefore, the factors of 1148 are: 1, 2, 4, 7, 14, 28, 41, 82, 164, 287, 574, 1148.

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 1148 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1148 ÷ 2 = 574

574 ÷ 2 = 287

287 ÷ 7 = 41

41 ÷ 41 = 1

The prime factors of 1148 are 2, 7, and 41. The prime factorization of 1148 is: 2² × 7 × 41.

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -

Step 1: Firstly, 1148 is divided by 2 to get 574.

Step 2: Now divide 574 by 2 to get 287.

Step 3: Then divide 287 by 7 to get 41. Here, 41 is a prime number, that cannot be divided anymore. So, the prime factorization of 1148 is: 2² × 7 × 41.

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 1148: (1, 1148), (2, 574), (4, 287), (7, 164), (14, 82), and (28, 41).
• Negative factor pairs of 1148: (-1, -1148), (-2, -574), (-4, -287), (-7, -164), (-14, -82), and (-28, -41).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1148 are 1, 2, 4, 7, 14, 28, 41, 82, 164, 287, 574, and 1148.

• Prime factors: The factors which are prime numbers. For example, 2, 7, and 41 are prime factors of 1148.

• Factor pairs: Two numbers in a pair that are multiplied to give the original number are called factor pairs. For example, the factor pairs of 1148 are (1, 1148), (2, 574), etc.
