The sum of factors of 3942: 1 + 2 + 3 + 6 + 9 + 18 + 219 + 438 + 657 + 1314 + 1971 + 3942 = 8580

How to Find Factors of 3942?

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

  • Finding factors using multiplication
     
  • Finding factors using division method
     
  • Prime factors and Prime factorization

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify pairs of numbers that multiply to give 3942. Identifying the numbers which are multiplied to get the number 3942 is the multiplication method.

Step 1: Multiply 3942 by 1, 3942 × 1 = 3942.

Step 2: Check for other numbers that give 3942 after multiplying

2 × 1971 = 3942

3 × 1314 = 3942

6 × 657 = 3942

9 × 438 = 3942

18 × 219 = 3942

Therefore, the positive factor pairs of 3942 are: (1, 3942), (2, 1971), (3, 1314), (6, 657), (9, 438), (18, 219).

For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given number 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 3942 by 1, 3942 ÷ 1 = 3942.

Step 2: Continue dividing 3942 by numbers until the remainder becomes 0.

3942 ÷ 1 = 3942

3942 ÷ 2 = 1971

3942 ÷ 3 = 1314

3942 ÷ 6 = 657

3942 ÷ 9 = 438

3942 ÷ 18 = 219

Therefore, the factors of 3942 are: 1, 2, 3, 6, 9, 18, 219, 438, 657, 1314, 1971, 3942.

Prime Factors and Prime Factorization

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

Using Prime Factorization: In this process, prime factors of 3942 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

3942 ÷ 2 = 1971

1971 ÷ 3 = 657

657 ÷ 3 = 219

219 is already a prime number.

The prime factors of 3942 are 2, 3, and 219.

The prime factorization of 3942 is: 2 × 3^2 × 219.

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following steps show

Step 1: Firstly, 3942 is divided by 2 to get 1971.

Step 2: Divide 1971 by 3 to get 657.

Step 3: Divide 657 by 3 to get 219. 219 cannot be divided anymore as it is prime. So, the prime factorization of 3942 is: 2 × 32 × 219.

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 3942: (1, 3942), (2, 1971), (3, 1314), (6, 657), (9, 438), and (18, 219).

Negative factor pairs of 3942: (-1, -3942), (-2, -1971), (-3, -1314), (-6, -657), (-9, -438), and (-18, -219).

Problem 2

A banner is 3942 square inches in area, and one side is 657 inches long. Find the length of the other side.

Okay, lets begin

6 inches.

Explanation

To find the length of the other side, we use the formula, Area = length × width

3942 = 657 × width

To find the value of width, we need to shift 657 to the left side.

3942/657 = width

Width = 6.
