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 1238. Identifying the numbers which are multiplied to get the number 1238 is the multiplication method.

Step 1: Multiply 1238 by 1, 1238 × 1 = 1238.

Step 2: Check for other numbers that give 1238 after multiplying 2 × 619 = 1238

Therefore, the positive factor pairs of 1238 are: (1, 1238) and (2, 619). All these factor pairs result in 1238. 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 the simple division method -

Step 1: Divide 1238 by 1, 1238 ÷ 1 = 1238.

Step 2: Continue dividing 1238 by the numbers until the remainder becomes 0.

1238 ÷ 1 = 1238

1238 ÷ 2 = 619

Therefore, the factors of 1238 are: 1, 2, 619, 1238.

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 1238 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.

1238 ÷ 2 = 619

619 ÷ 619 = 1

The prime factors of 1238 are 2 and 619. The prime factorization of 1238 is: 2 × 619.

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

Step 1: Firstly, 1238 is divided by 2 to get 619.

Step 2: Now divide 619 by 619 to get 1. Here, 619 is the largest prime number that cannot be divided anymore. So, the prime factorization of 1238 is: 2 × 619.

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 1238: (1, 1238) and (2, 619).

• Negative factor pairs of 1238: (-1, -1238) and (-2, -619).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1238 are 1, 2, 619, and 1238.

• Prime factors: The factors which are prime numbers. For example, 2 and 619 are prime factors of 1238.

• 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 1238 are (1, 1238) and (2, 619).

• Prime factorization: The expression of a number as a product of its prime factors. For example, the prime factorization of 1238 is 2 × 619.

• Multiples: A multiple of a number is the product of that number and an integer. For example, 1238 is a multiple of 2.
