The sum of factors of 812: 1 + 2 + 4 + 7 + 14 + 29 + 58 + 116 + 203 + 406 + 812 = 1652
How to Find Factors of 812?
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 the pairs of numbers that are multiplied to give 812. Identifying the numbers which are multiplied to get the number 812 is the multiplication method.
Step 1: Multiply 812 by 1, 812 × 1 = 812.
Step 2: Check for other numbers that give 812 after multiplying
2 × 406 = 812
4 × 203 = 812
7 × 116 = 812
14 × 58 = 812
29 × 28 = 812
Therefore, the positive factor pairs of 812 are: (1, 812), (2, 406), (4, 203), (7, 116), (14, 58), and (29, 28).
For every positive factor, there is a negative factor.
Finding Factors Using Division Method
Dividing the given numbers with the 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 812 by 1, 812 ÷ 1 = 812.
Step 2: Continue dividing 812 by the numbers until the remainder becomes 0.
812 ÷ 1 = 812
812 ÷ 2 = 406
812 ÷ 4 = 203
812 ÷ 7 = 116
812 ÷ 14 = 58
812 ÷ 29 = 28
Therefore, the factors of 812 are: 1, 2, 4, 7, 14, 29, 58, 116, 203, 406, and 812.
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 factor tree
Using Prime Factorization: In this process, prime factors of 812 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
812 ÷ 2 = 406
406 ÷ 2 = 203
203 ÷ 7 = 29
29 ÷ 29 = 1
The prime factors of 812 are 2, 7, and 29.
The prime factorization of 812 is: 2² × 7 × 29.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 812 is divided by 2 to get 406.
Step 2: Now divide 406 by 2 to get 203.
Step 3: Then divide 203 by 7 to get 29. Here, 29 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 812 is: 2² × 7 × 29.
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 812: (1, 812), (2, 406), (4, 203), (7, 116), (14, 58), and (29, 28).
Negative factor pairs of 812: (-1, -812), (-2, -406), (-4, -203), (-7, -116), (-14, -58), and (-29, -28).
Common Mistakes and How to Avoid Them in Factors of 812
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 812, 1 and 812 are also factors.
Mistake 2
Missing Negative Factors
We have used only to mention positive factors every time. There are also negative factors; always check whether you have mentioned negative factors.
For example, the factors of 812 consist of -1, -2, -4, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions also as factors. Only whole numbers can be a factor.
For example, thinking 1.5 as a factor, because 812/1.5 results in a non-whole number.
Mistake 4
Confusing Factors With Prime Numbers
Remember that factors can be any whole numbers, not only just primes.
For example, thinking all the factors of 812 are prime numbers.
For example, 2, 7, and 29 are the prime factors of 812, but it has other factors like 4, 58.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 812 as 2² × 7 × 29 and missing all the key factors.
Factors of 812 Examples
Problem 1
There are 812 candies to be packed into boxes with each box holding 29 candies. How many full boxes can be packed?
28 full boxes can be packed.
Explanation
To find the number of full boxes, divide the total candies by the number of candies each box holds.
812/29 = 28
Problem 2
A rectangular plot has a length of 58 meters and a total area of 812 square meters. Find the width.
14 meters.
Explanation
To find the width of the plot, we use the formula, Area = length × width
812 = 58 × width
To find the value of width, divide the area by the length.
812/58 = width
Width = 14.
Problem 3
There are 116 oranges and 812 boxes. How many boxes will have oranges if each box can hold only one orange?
116 boxes will have oranges.
Explanation
To find out how many boxes will have oranges, divide the total number of oranges by the capacity of each box.
812/116 = 7
Problem 4
A class of 406 students needs to be divided into 29 groups. How many students will be in each group?
14 students will be in each group.
Explanation
Dividing the students by the total groups gives the number of students in each group.
406/29 = 14
Problem 5
A warehouse has 58 shelves and 812 items. How many items will be on each shelf if distributed equally?
Each shelf will have 14 items.
Explanation
Divide the total items by the number of shelves.
812/58 = 14
