Prime factorization of 1551: 3 × 11 × 47.

The sum of factors of 1551: 1 + 3 + 11 + 33 + 47 + 141 + 517 + 1551 = 2304

Factors can be found using different methods. Mentioned below are some commonly used methods:

1. Finding factors using multiplication
2. Finding factors using the 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 1551. Identifying the numbers which are multiplied to get the number 1551 is the multiplication method.

Step 1: Multiply 1551 by 1, 1551 × 1 = 1551.

Step 2: Check for other numbers that give 1551 after multiplying:

3 × 517 = 1551

11 × 141 = 1551

33 × 47 = 1551

Therefore, the positive factor pairs of 1551 are: (1, 1551), (3, 517), (11, 141), and (33, 47). 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 using a simple division method -

Step 1: Divide 1551 by 1, 1551 ÷ 1 = 1551.

Step 2: Continue dividing 1551 by the numbers until the remainder becomes 0.

1551 ÷ 1 = 1551

1551 ÷ 3 = 517

1551 ÷ 11 = 141

1551 ÷ 33 = 47

Therefore, the factors of 1551 are: 1, 3, 11, 33, 47, 141, 517, 1551.

The factors can be found by dividing them 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 1551 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1551 ÷ 3 = 517

517 ÷ 11 = 47

47 ÷ 47 = 1

The prime factors of 1551 are 3, 11, and 47. The prime factorization of 1551 is: 3 × 11 × 47.

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

Step 1: Firstly, 1551 is divided by 3 to get 517.

Step 2: Now divide 517 by 11 to get 47.

Step 3: Here, 47 is the smallest prime number, which cannot be divided anymore. So, the prime factorization of 1551 is: 3 × 11 × 47.

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 1551: (1, 1551), (3, 517), (11, 141), and (33, 47).

• Negative factor pairs of 1551: (-1, -1551), (-3, -517), (-11, -141), and (-33, -47).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1551 are 1, 3, 11, 33, 47, 141, 517, and 1551.

• Prime factors: The factors which are prime numbers. For example, 3, 11, and 47 are prime factors of 1551.

• 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 1551 are (1, 1551), (3, 517), etc.

• Prime factorization: A method of writing a number as the product of its prime factors. For example, 1551 can be written as 3 × 11 × 47.

• Negative factors: Factors that are negative counterparts of positive factors. For example, the negative factors of 1551 include -1, -3, -11, etc.
