The sum of factors of 1562: 1 + 2 + 17 + 23 + 34 + 46 + 391 + 782 + 1562 = 2858

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 1562. Identifying the numbers which are multiplied to get the number 1562 is the multiplication method.

Step 1: Multiply 1562 by 1, 1562 × 1 = 1562.

Step 2: Check for other numbers that give 1562 after multiplying

2 × 781 = 1562

17 × 92 = 1562

23 × 68 = 1562

Therefore, the positive factor pairs of 1562 are: (1, 1562), (2, 781), (17, 92), and (23, 68). All these factor pairs result in 1562. 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 1562 by 1, 1562 ÷ 1 = 1562.

Step 2: Continue dividing 1562 by the numbers until the remainder becomes 0.

1562 ÷ 1 = 1562

1562 ÷ 2 = 781

1562 ÷ 17 = 92

1562 ÷ 23 = 68

Therefore, the factors of 1562 are: 1, 2, 17, 23, 34, 46, 391, 782, and 1562.

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 1562 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.

1562 ÷ 2 = 781

781 ÷ 17 = 46

46 ÷ 23 = 2

2 ÷ 2 = 1

The prime factors of 1562 are 2, 17, and 23. The prime factorization of 1562 is: 2 × 17 × 23.

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

Step 1: Firstly, 1562 is divided by 2 to get 781.

Step 2: Now divide 781 by 17 to get 46.

Step 3: Then divide 46 by 23 to get 2. Here, 2 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1562 is: 2 × 17 × 23.

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 1562: (1, 1562), (2, 781), (17, 92), and (23, 68).

• Negative factor pairs of 1562: (-1, -1562), (-2, -781), (-17, -92), and (-23, -68).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1562 are 1, 2, 17, 23, 34, 46, 391, 782, and 1562.

• Prime factors: The factors which are prime numbers. For example, 2, 17, and 23 are prime factors of 1562.

• 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 1562 are (1, 1562), (2, 781), etc.

• Prime factorization: The expression of a number as a product of its prime factors. For 1562, it is 2 × 17 × 23.

• Negative factors: Factors of a number that are negative. For 1562, they are -1, -2, -17, -23, -34, -46, -391, -782, and -1562.
