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 1538. Identifying the numbers which are multiplied to get the number 1538 is the multiplication method.

Step 1: Multiply 1538 by 1, 1538 × 1 = 1538.

Step 2: Check for other numbers that give 1538 after multiplying

2 × 769 = 1538

Therefore, the positive factor pairs of 1538 are: (1, 1538) and (2, 769). All these factor pairs result in 1538. For every positive factor, there is a negative factor.

Dividing the given numbers 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 a simple division method -

Step 1: Divide 1538 by 1, 1538 ÷ 1 = 1538.

Step 2: Continue dividing 1538 by the numbers until the remainder becomes 0.

1538 ÷ 1 = 1538

1538 ÷ 2 = 769

Therefore, the factors of 1538 are: 1, 2, 769, and 1538.

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 1538 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.

1538 ÷ 2 = 769

769 ÷ 769 = 1

The prime factors of 1538 are 2 and 769. The prime factorization of 1538 is: 2 × 769.

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

Step 1: Firstly, 1538 is divided by 2 to get 769. 769 is a prime number, so it cannot be divided further. So, the prime factorization of 1538 is: 2 × 769.

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 1538: (1, 1538) and (2, 769).

• Negative factor pairs of 1538: (-1, -1538) and (-2, -769).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1538 are 1, 2, 769, and 1538.

• Prime factors: The factors which are prime numbers. For example, 2 and 769 are prime factors of 1538.

• 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 1538 are (1, 1538) and (2, 769).

• Prime factorization: The expression of a number as the product of its prime factors. For example, the prime factorization of 1538 is 2 × 769.

• Multiple: A number that can be divided by another number without leaving a remainder. For example, 1538 is a multiple of 2.
