Prime factorization of 663: 3 × 13 × 17.

The sum of factors of 663: 1 + 3 + 13 + 17 + 39 + 51 + 221 + 663 = 1,008

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 multiply to give 663. Identifying the numbers which are multiplied to get the number 663 is the multiplication method.

Step 1: Multiply 663 by 1, 663 × 1 = 663.

Step 2: Check for other numbers that give 663 after multiplying

3 × 221 = 663

13 × 51 = 663

17 × 39 = 663

Therefore, the positive factor pairs of 663 are: (1, 663), (3, 221), (13, 51), (17, 39).

All these factor pairs result in 663. 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 in whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 663 by 1, 663 ÷ 1 = 663.

Step 2: Continue dividing 663 by the numbers until the remainder becomes 0.

663 ÷ 1 = 663

663 ÷ 3 = 221

663 ÷ 13 = 51

663 ÷ 17 = 39

Therefore, the factors of 663 are: 1, 3, 13, 17, 39, 51, 221, 663.

The factors can be found by dividing with prime numbers. We can find the prime factors using the following methods:

1. Using prime factorization
2. Using factor tree

Using Prime Factorization: In this process, prime factors of 663 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

663 ÷ 3 = 221

221 ÷ 13 = 17

17 ÷ 17 = 1

The prime factors of 663 are 3, 13, and 17.

The prime factorization of 663 is: 3 × 13 × 17.

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

Step 1: Firstly, 663 is divided by 3 to get 221.

Step 2: Now divide 221 by 13 to get 17.

Step 3: Here, 17 is a prime number and cannot be divided further. So, the prime factorization of 663 is: 3 × 13 × 17.

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 663: (1, 663), (3, 221), (13, 51), and (17, 39).
• Negative factor pairs of 663: (-1, -663), (-3, -221), (-13, -51), and (-17, -39).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 663 are 1, 3, 13, 17, 39, 51, 221, and 663.

• Prime factors: The factors which are prime numbers. For example, 3, 13, and 17 are prime factors of 663.

• 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 663 are (1, 663), (3, 221), etc.

• Prime factorization: Breaking down a number into its prime factors. For 663, this is 3 × 13 × 17.

• Multiples: Numbers that can be obtained by multiplying the original number by any integer. For example, 663 is a multiple of 3.
