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 1566. Identifying the numbers which are multiplied to get the number 1566 is the multiplication method.

Step 1: Multiply 1566 by 1, 1566 × 1 = 1566.

Step 2: Check for other numbers that give 1566 after multiplying:     

2 × 783 = 1566     

3 × 522 = 1566     

6 × 261 = 1566    

 9 × 174 = 1566     

18 × 87 = 1566     

29 × 54 = 1566

Therefore, the positive factor pairs of 1566 are: (1, 1566), (2, 783), (3, 522), (6, 261), (9, 174), (18, 87), and (29, 54). 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 1566 by 1, 1566 ÷ 1 = 1566.

Step 2: Continue dividing 1566 by the numbers until the remainder becomes 0.

1566 ÷ 1 = 1566

1566 ÷ 2 = 783

1566 ÷ 3 = 522

1566 ÷ 6 = 261

1566 ÷ 9 = 174

1566 ÷ 18 = 87

1566 ÷ 29 = 54

Therefore, the factors of 1566 are: 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522, 783, 1566.

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 1566 divide the number to break it down in the multiplication form of prime factors until the remainder becomes 1.

1566 ÷ 2 = 783

783 ÷ 3 = 261

261 ÷ 3 = 87

87 ÷ 3 = 29

29 ÷ 29 = 1

The prime factors of 1566 are 2, 3, and 29. The prime factorization of 1566 is: 2 × 3 × 3 × 29.

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

Step 1: Firstly, 1566 is divided by 2 to get 783.

Step 2: Now divide 783 by 3 to get 261.

Step 3: Then divide 261 by 3 to get 87.

Step 4: Divide 87 by 3 to get 29. Here, 29 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1566 is: 2 × 3 × 3 × 29.

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 1566: (1, 1566), (2, 783), (3, 522), (6, 261), (9, 174), (18, 87), and (29, 54).

• Negative factor pairs of 1566: (-1, -1566), (-2, -783), (-3, -522), (-6, -261), (-9, -174), (-18, -87), and (-29, -54).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1566 are 1, 2, 3, 6, etc.

• Prime factors: The factors which are prime numbers. For example, 2, 3, and 29 are prime factors of 1566.

• 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 1566 are (1, 1566), (2, 783), etc.

• Prime factorization: The expression of a number as the product of its prime numbers. For example, the prime factorization of 1566 is 2 × 3 × 3 × 29.

• Divisibility: A measure of whether a number can be evenly divided by another without leaving a remainder.
