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 1542. Identifying the numbers which are multiplied to get the number 1542 is the multiplication method.

Step 1: Multiply 1542 by 1, 1542 × 1 = 1542.

Step 2: Check for other numbers that give 1542 after multiplying

2 × 771 = 1542

3 × 514 = 1542

6 × 257 = 1542

Therefore, the positive factor pairs of 1542 are: (1, 1542), (2, 771), (3, 514), (6, 257). All these factor pairs result in 1542. 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 simple division method:

Step 1: Divide 1542 by 1, 1542 ÷ 1 = 1542.

Step 2: Continue dividing 1542 by the numbers until the remainder becomes 0.

1542 ÷ 1 = 1542

1542 ÷ 2 = 771

1542 ÷ 3 = 514

1542 ÷ 6 = 257

Therefore, the factors of 1542 are: 1, 2, 3, 6, 257, 514, 771, 1542.

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 1542 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1542 ÷ 2 = 771

771 ÷ 3 = 257

257 ÷ 257 = 1

The prime factors of 1542 are 2, 3, and 257. The prime factorization of 1542 is: 2 × 3 × 257.

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

Step 1: Firstly, 1542 is divided by 2 to get 771.

Step 2: Now divide 771 by 3 to get 257.

Step 3: Divide 257 by 257 to get 1. Here, 257 is a prime number, that cannot be divided anymore. So, the prime factorization of 1542 is: 2 × 3 × 257.

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 1542: (1, 1542), (2, 771), (3, 514), (6, 257).

• Negative factor pairs of 1542: (-1, -1542), (-2, -771), (-3, -514), (-6, -257).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1542 are 1, 2, 3, 6, 257, 514, 771, and 1542.

• Prime factors: The factors which are prime numbers. For example, 2, 3, and 257 are prime factors of 1542.

• 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 1542 are (1, 1542), (2, 771), etc.

• Prime factorization: Expressing a number as the product of its prime factors. For example, the prime factorization of 1542 is 2 × 3 × 257.

• Multiple: A number that can be divided by another number without leaving a remainder. For example, 1542 is a multiple of 3.
