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 1544. Identifying the numbers which are multiplied to get the number 1544 is the multiplication method.

Step 1: Multiply 1544 by 1, 1544 × 1 = 1544.

Step 2: Check for other numbers that give 1544 after multiplying

2 × 772 = 1544

4 × 386 = 1544

8 × 193 = 1544

Therefore, the positive factor pairs of 1544 are: (1, 1544), (2, 772), (4, 386), (8, 193). 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 1544 by 1, 1544 ÷ 1 = 1544.

Step 2: Continue dividing 1544 by the numbers until the remainder becomes 0.

1544 ÷ 1 = 1544

1544 ÷ 2 = 772

1544 ÷ 4 = 386

1544 ÷ 8 = 193

Therefore, the factors of 1544 are: 1, 2, 4, 8, 193, 386, 772, 1544.

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 1544 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1544 ÷ 2 = 772

772 ÷ 2 = 386

386 ÷ 2 = 193

193 ÷ 193 = 1

The prime factors of 1544 are 2 and 193. The prime factorization of 1544 is: (2³ x 193).

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

Step 1: Firstly, 1544 is divided by 2 to get 772.

Step 2: Now divide 772 by 2 to get 386.

Step 3: Then divide 386 by 2 to get 193. Here, 193 is a prime number and cannot be divided anymore. So, the prime factorization of 1544 is: (2³ x 193).

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 1544: (1, 1544), (2, 772), (4, 386), (8, 193).

• Negative factor pairs of 1544: (-1, -1544), (-2, -772), (-4, -386), (-8, -193).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1544 are 1, 2, 4, 8, 193, 386, 772, and 1544.

• Prime factors: The factors which are prime numbers. For example, 2 and 193 are prime factors of 1544.

• 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 1544 are (1, 1544), (2, 772), etc.

• Prime factorization: Breaking down a number into its prime factors. For example, the prime factorization of 1544 is (2³ x193).

• Multiplication method: A way to find factors by identifying pairs of numbers that multiply to the given number. For example, using multiplication to find factors of 1544 like (4, 386).
