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 1223. Identifying the numbers which are multiplied to get the number 1223 is the multiplication method.

Step 1: Multiply 1223 by 1, 1223 × 1 = 1223.

Step 2: Check for other numbers that give 1223 after multiplying 17 × 71 = 1223

Therefore, the positive factor pairs of 1223 are: (1, 1223) and (17, 71). 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 in whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 1223 by 1, 1223 ÷ 1 = 1223.

Step 2: Continue dividing 1223 by the numbers until the remainder becomes 0.

1223 ÷ 1 = 1223

1223 ÷ 17 = 71

1223 ÷ 71 = 17

Therefore, the factors of 1223 are: 1, 17, 71, and 1223.

The factors can be found by dividing it with a prime number. 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 1223 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.

1223 ÷ 17 = 71

71 ÷ 71 = 1

The prime factors of 1223 are 17 and 71. The prime factorization of 1223 is: 17 × 71.

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

Step 1: Firstly, 1223 is divided by 17 to get 71.

Step 2: Now divide 71 by 71 to get 1. Here, 71 is a prime number and cannot be divided anymore. So, the prime factorization of 1223 is: 17 × 71.

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 1223: (1, 1223) and (17, 71).
• Negative factor pairs of 1223: (-1, -1223) and (-17, -71).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1223 are 1, 17, 71, and 1223.

• Prime factors: The factors which are prime numbers. For example, 17 and 71 are prime factors of 1223.

• 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 1223 are (1, 1223) and (17, 71).

• Prime factorization: Expressing a number as a product of its prime factors. For example, the prime factorization of 1223 is 17 × 71.

• Multiples: A multiple is the product of a number and an integer. For example, 1223 is a multiple of 17 and 71.
