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 1558. Identifying the numbers which are multiplied to get the number 1558 is the multiplication method.

Step 1: Multiply 1558 by 1, 1558 × 1 = 1558.

Step 2: Check for other numbers that give 1558 after multiplying 2 × 779 = 1558

Therefore, the positive factor pairs of 1558 are: (1, 1558), (2, 779). All these factor pairs result in 1558. 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 1558 by 1, 1558 ÷ 1 = 1558.

Step 2: Continue dividing 1558 by the numbers until the remainder becomes 0.

1558 ÷ 1 = 1558

1558 ÷ 2 = 779

Therefore, the factors of 1558 are: 1, 2, 779, 1558.

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 1558 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1558 ÷ 2 = 779

779 ÷ 779 = 1

The prime factors of 1558 are 2 and 779. The prime factorization of 1558 is: 2 × 779.

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

Step 1: Firstly, 1558 is divided by 2 to get 779.

Step 2: Since 779 is a prime number, it cannot be divided further except by itself. So, the prime factorization of 1558 is: 2 × 779.

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 1558: (1, 1558), (2, 779).

• Negative factor pairs of 1558: (-1, -1558), (-2, -779).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1558 are 1, 2, 779, and 1558.

• Prime factors: The factors which are prime numbers. For example, 2 and 779 are prime factors of 1558.

• 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 1558 are (1, 1558) and (2, 779).

• Prime factorization: The expression of a number as a product of its prime factors. For example, the prime factorization of 1558 is 2 × 779.

• Multiple: A number that can be divided by another number without a remainder. For example, 1558 is a multiple of 2 and 779.
