Factors can be found using different methods. Mentioned below are some commonly used methods:

1. Finding factors using multiplication
2. Finding factors using the 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 1565. Identifying the numbers which are multiplied to get the number 1565 is the multiplication method.

Step 1: Multiply 1565 by 1, 1565 × 1 = 1565.

Step 2: Check for other numbers that give 1565 after multiplying

5 × 313 = 1565

Therefore, the positive factor pairs of 1565 are: (1, 1565) and (5, 313). All these factor pairs result in 1565. For every positive factor, there is a negative factor.

Dividing the given number with 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 the simple division method -

Step 1: Divide 1565 by 1, 1565 ÷ 1 = 1565.

Step 2: Continue dividing 1565 by the numbers until the remainder becomes 0.

1565 ÷ 1 = 1565

1565 ÷ 5 = 313

1565 ÷ 313 = 5

Therefore, the factors of 1565 are: 1, 5, 313, and 1565.

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 1565 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1565 ÷ 5 = 313

313 ÷ 313 = 1

The prime factors of 1565 are 5 and 313. The prime factorization of 1565 is: 5 × 313.

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

Step 1: Firstly, 1565 is divided by 5 to get 313.

Step 2: Now divide 313 by itself as it is a prime number. Here, 313 is a prime number and cannot be divided further. So, the prime factorization of 1565 is: 5 × 313.

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 1565: (1, 1565) and (5, 313).

• Negative factor pairs of 1565: (-1, -1565) and (-5, -313).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1565 are 1, 5, 313, and 1565.

• Prime factors: The factors which are prime numbers. For example, 5 and 313 are prime factors of 1565.

• 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 1565 are (1, 1565) and (5, 313).

• Prime factorization: A method of expressing a number as the product of its prime factors. For example, 1565 is 5 × 313.

• Multiplication Method: A way to find factors by identifying pairs of numbers that multiply to give a specific number. For example, finding pairs for 1565 as (1, 1565) and (5, 313).
