The sum of factors of 1528: 1 + 2 + 4 + 7 + 14 + 19 + 28 + 38 + 76 + 133 + 266 + 361 + 532 + 685 + 1528 = 3694.

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 1528. Identifying the numbers which are multiplied to get the number 1528 is the multiplication method.

Step 1: Multiply 1528 by 1, 1528 × 1 = 1528.

Step 2: Check for other numbers that give 1528 after multiplying

2 × 764 = 1528

4 × 382 = 1528

7 × 218 = 1528

14 × 109 = 1528

19 × 80 = 1528

28 × 54.5714 = 1528 (not a whole number, so skip)

38 × 40.2105 = 1528 (not a whole number, so skip)

Therefore, the positive factor pairs of 1528 are: (1, 1528), (2, 764), (4, 382), (7, 218), (14, 109), (19, 80). All these factor pairs result in 1528. For every positive factor, there is a negative factor.

Dividing the given number 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 1528 by 1, 1528 ÷ 1 = 1528.

Step 2: Continue dividing 1528 by the numbers until the remainder becomes 0.

1528 ÷ 1 = 1528

1528 ÷ 2 = 764

1528 ÷ 4 = 382

1528 ÷ 7 = 218

1528 ÷ 14 = 109

1528 ÷ 19 = 80

Therefore, the factors of 1528 are: 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 361, 532, 685, 1528.

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 1528 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1528 ÷ 2 = 764

764 ÷ 2 = 382

382 ÷ 2 = 191

191 ÷ 7 = 27.2857 (not a whole number)

191 ÷ 19 = 10.0526 (not a whole number)

Therefore, the prime factors of 1528 are 2, 7, and 19. The prime factorization of 1528 is: 2 × 2 × 7 × 19.

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

Step 1: Firstly, 1528 is divided by 2 to get 764.

Step 2: Now divide 764 by 2 to get 382.

Step 3: Then divide 382 by 2 to get 191. Here, 191 is a prime number and cannot be divided further by any smaller primes like 2, 3, 5, 7, 11, 13. So, the prime factorization of 1528 is: 2 × 2 × 7 × 19.

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 1528: (1, 1528), (2, 764), (4, 382), (7, 218), (14, 109), (19, 80).

• Negative factor pairs of 1528: (-1, -1528), (-2, -764), (-4, -382), (-7, -218), (-14, -109), (-19, -80).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1528 are 1, 2, 4, 7, 14, and so on.

• Prime factors: The factors which are prime numbers. For example, 2, 7, and 19 are prime factors of 1528.

• 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 1528 are (1, 1528), (2, 764), etc.

• Prime factorization: The process of expressing a number as the product of its prime factors. For example, the prime factorization of 1528 is 2 × 2 × 7 × 19.

• Multiplication method: A method to find factors by identifying pairs of numbers that multiply to give the original number.
