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 1541. Identifying the numbers which are multiplied to get the number 1541 is the multiplication method.

Step 1: Multiply 1541 by 1, 1541 × 1 = 1541.

Step 2: Check for other numbers that give 1541 after multiplying 23 × 67 = 1541

Therefore, the positive factor pairs of 1541 are: (1, 1541), and (23, 67). All these factor pairs result in 1541. 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 1541 by 1, 1541 ÷ 1 = 1541.

Step 2: Continue dividing 1541 by the numbers until the remainder becomes 0.

1541 ÷ 1 = 1541

1541 ÷ 23 = 67

1541 ÷ 67 = 23

Therefore, the factors of 1541 are: 1, 23, 67, and 1541.

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 1541 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1541 ÷ 23 = 67

67 ÷ 67 = 1

The prime factors of 1541 are 23 and 67. The prime factorization of 1541 is: 23 × 67.

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

Step 1: Firstly, 1541 is divided by 23 to get 67.

Step 2: Now divide 67 by 67 to get 1. Here, 67 is a prime number that cannot be divided anymore. So, the prime factorization of 1541 is: 23 × 67.

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 1541: (1, 1541), and (23, 67).

• Negative factor pairs of 1541: (-1, -1541), and (-23, -67).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1541 are 1, 23, 67, and 1541.

• Prime factors: The factors which are prime numbers. For example, 23 and 67 are prime factors of 1541.

• 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 1541 are (1, 1541), and (23, 67).

• Prime factorization: The expression of a number as a product of its prime factors. For instance, the prime factorization of 1541 is 23 × 67.

• Multiplication method: A method of finding factors by identifying pairs of numbers that multiply to give the original number.
