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 1258. Identifying the numbers which are multiplied to get the number 1258 is the multiplication method.

Step 1: Multiply 1258 by 1, 1258 × 1 = 1258.

Step 2: Check for other numbers that give 1258 after multiplying 2 × 629 = 1258

Therefore, the positive factor pairs of 1258 are: (1, 1258) and (2, 629). All these factor pairs result in 1258. 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 that result as whole numbers as factors. Factors can be calculated by following simple division method -

Step 1: Divide 1258 by 1, 1258 ÷ 1 = 1258.

Step 2: Continue dividing 1258 by the numbers until the remainder becomes 0.

1258 ÷ 1 = 1258

1258 ÷ 2 = 629

Therefore, the factors of 1258 are: 1, 2, 629, and 1258.

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 1258 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1258 ÷ 2 = 629

629 is a prime number and cannot be divided further. The prime factors of 1258 are 2 and 629. The prime factorization of 1258 is: 2 × 629.

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

Step 1: Firstly, 1258 is divided by 2 to get 629. Here, 629 is a prime number that cannot be divided further. So, the prime factorization of 1258 is: 2 × 629.

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 1258: (1, 1258) and (2, 629).

• Negative factor pairs of 1258: (-1, -1258) and (-2, -629).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1258 are 1, 2, 629, and 1258.

• Prime factors: The factors which are prime numbers. For example, 2 and 629 are prime factors of 1258.

• 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 1258 are (1, 1258) and (2, 629).

• Prime factorization: Expressing a number as the product of its prime factors. For example, the prime factorization of 1258 is 2 × 629.

• Negative factors: The negative counterparts of positive factors. For example, the negative factors of 1258 include -1, -2, -629, and -1258.
