The sum of factors of 8400: Calculating the sum requires summing all positive factors.
How to Find Factors of 8400?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using the division method
- Prime factors and prime factorization
Finding Factors Using Multiplication
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 8400. Identifying the numbers which are multiplied to get the number 8400 is the multiplication method.
Step 1: Multiply 8400 by 1, 8400 × 1 = 8400.
Step 2: Check for other numbers that give 8400 after multiplying.
For example, 2 × 4200 = 84003 × 2800 = 8400, etc.
Therefore, the positive factor pairs of 8400 are (1, 8400), (2, 4200), (3, 2800), and so on.
For every positive factor, there is a negative factor.
Finding Factors Using Division Method
Dividing the given numbers with whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method
Step 1: Divide 8400 by 1, 8400 ÷ 1 = 8400.
Step 2: Continue dividing 8400 by the numbers until the remainder becomes 0.
For example, 8400 ÷ 2 = 4200, 8400 ÷ 3 = 2800, etc.
Therefore, the factors of 8400 include numbers like 1, 2, 3, 4, 5, 6, 7, 8, and so on.
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
- Using a factor tree
Using Prime Factorization: In this process, prime factors of 8400 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
8400 ÷ 2 = 4200
4200 ÷ 2 = 2100
2100 ÷ 2 = 1050
1050 ÷ 2 = 525
525 ÷ 3 = 175
175 ÷ 5 = 35
35 ÷ 5 = 7
7 ÷ 7 = 1
The prime factors of 8400 are 2, 3, 5, and 7.
The prime factorization of 8400 is: 24 × 3 × 52 × 7.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 8400 is divided by 2 to get 4200.
Step 2: Now divide 4200 by 2 to get 2100.
Step 3: Then divide 2100 by 2 to get 1050.
Step 4: Divide 1050 by 2 to get 525.
Step 5: Divide 525 by 3 to get 175.
Step 6: Divide 175 by 5 to get 35.
Step 7: Divide 35 by 5 to get 7. Here, 7 is the smallest prime number that cannot be divided anymore.
So, the prime factorization of 8400 is: 24 × 3 × 52 × 7.
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 8400 include: (1, 8400), (2, 4200), (3, 2800), etc.
Negative factor pairs of 8400 include: (-1, -8400), (-2, -4200), (-3, -2800), etc.
Common Mistakes and How to Avoid Them in Factors of 8400
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
Mistake 1
Forgetting the number itself and 1 is a factor
Children might forget to add the given number itself and 1 as a factor. The number itself and 1 are the factors for every number. Always remember to include 1 and the number itself.
For example, in factors of 8400, 1 and 8400 are also factors.
Factors of 8400 Examples
Problem 1
There are 420 friends and 8400 candies. How will they divide them equally?
They will get 20 candies each.
Explanation
To divide the candies equally, we need to divide the total candies with the number of friends. 8400/420 = 20
Problem 2
A field is rectangular, the length of the field is 120 meters, and the total area is 8400 square meters. Find the width?
70 meters.
Explanation
To find the width of the field, we use the formula,
Area = length × width
8400 = 120 × width
To find the value of width, we need to shift 120 to the left side.
8400/120 = width
Width = 70.
Problem 3
There are 80 bags and 8400 marbles. How many marbles will be in each bag?
Each bag will have 105 marbles.
Explanation
To find the marbles in each bag, divide the total marbles with the bags. 8400/80 = 105
Problem 4
In a class, there are 8400 students, and 210 groups. How many students are there in each group?
There are 40 students in each group.
Explanation
Dividing the students with the total groups, we will get the number of students in each group. 8400/210 = 40
Problem 5
8400 books need to be arranged in 150 shelves. How many books will go on each shelf?
Each of the shelves has 56 books.
Explanation
Divide total books with shelves. 8400/150 = 56
