The sum of factors of 1556: 1 + 2 + 4 + 389 + 778 + 1556 = 2730

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 1556. Identifying the numbers which are multiplied to get the number 1556 is the multiplication method.

Step 1: Multiply 1556 by 1, 1556 × 1 = 1556.

Step 2: Check for other numbers that give 1556 after multiplying

2 × 778 = 1556

4 × 389 = 1556

Therefore, the positive factor pairs of 1556 are: (1, 1556), (2, 778), and (4, 389). All these factor pairs result in 1556. 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 1556 by 1, 1556 ÷ 1 = 1556.

Step 2: Continue dividing 1556 by the numbers until the remainder becomes 0.

1556 ÷ 1 = 1556

1556 ÷ 2 = 778

1556 ÷ 4 = 389

Therefore, the factors of 1556 are: 1, 2, 4, 389, 778, 1556.

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 1556 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1556 ÷ 2 = 778

778 ÷ 2 = 389

389 ÷ 389 = 1

The prime factors of 1556 are 2 and 389. The prime factorization of 1556 is: 2² × 389.

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

Step 1: Firstly, 1556 is divided by 2 to get 778.

Step 2: Now divide 778 by 2 to get 389.

Step 3: Divide 389 by 389 to get 1. Here, 389 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1556 is: 2² × 389.

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 1556: (1, 1556), (2, 778), and (4, 389).

• Negative factor pairs of 1556: (-1, -1556), (-2, -778), and (-4, -389).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1556 are 1, 2, 4, 389, 778, and 1556.

• Prime factors: The factors which are prime numbers. For example, 2 and 389 are prime factors of 1556.

• 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 1556 are (1, 1556), (2, 778), etc.

• Prime factorization: The expression of a number as the product of its prime factors. For example, the prime factorization of 1556 is 2² × 389.

• Negative factors: Factors that are negative numbers. For example, -1, -2, -4, -389, -778, and -1556 are negative factors of 1556.
