Factors of 783
Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 783, how they are used in real life, and tips to learn them quickly.
What are the Factors of 783?
The numbers that divide 783 evenly are known as factors of 783.
A factor of 783 is a number that divides the number without remainder.
The factors of 783 are 1, 3, 9, 87, 261, and 783.
Negative factors of 783: -1, -3, -9, -87, -261, and -783.
Prime factors of 783: 3 and 29.
Prime factorization of 783: 3² × 29.
The sum of factors of 783: 1 + 3 + 9 + 87 + 261 + 783 = 1144
How to Find Factors of 783?
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 783. Identifying the numbers which are multiplied to get the number 783 is the multiplication method.
Step 1: Multiply 783 by 1, 783 × 1 = 783.
Step 2: Check for other numbers that give 783 after multiplying
3 × 261 = 783
9 × 87 = 783
Therefore, the positive factor pairs of 783 are: (1, 783), (3, 261), (9, 87).
All these factor pairs result in 783.
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 783 by 1, 783 ÷ 1 = 783.
Step 2: Continue dividing 783 by the numbers until the remainder becomes 0.
783 ÷ 1 = 783
783 ÷ 3 = 261
783 ÷ 9 = 87
Therefore, the factors of 783 are: 1, 3, 9, 87, 261, and 783.
Prime Factors and Prime Factorization
The factors can be found by dividing it with a prime number. 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 783 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
783 ÷ 3 = 261
261 ÷ 3 = 87
87 ÷ 3 = 29
29 is a prime number, so it cannot be divided further.
The prime factors of 783 are 3 and 29.
The prime factorization of 783 is: 3² × 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, 783 is divided by 3 to get 261.
Step 2: Now divide 261 by 3 to get 87.
Step 3: Divide 87 by 3 to get 29. Here, 29 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 783 is: 3² × 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 783: (1, 783), (3, 261), (9, 87).
Negative factor pairs of 783: (-1, -783), (-3, -261), (-9, -87).
Common Mistakes and How to Avoid Them in Factors of 783
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
People 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 783, 1 and 783 are also factors.
Mistake 2
Missing Negative Factors
We often mention only positive factors. There are also negative factors, always check whether you have mentioned negative factors.
For example, the factors of 783 consist of -1, -3, -9, etc.
Mistake 3
Including the Fraction
People might sometimes add fractions also as factors. Only whole numbers can be a factor.
For example, thinking 1.5 as a factor, because 783/1.5 = 522, and it is not a 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 783 are prime numbers.
For example, 3 and 29 are the prime factors of 783, but it has other factors like 9 and 87.
Mistake 5
Mistake in Factorization
People might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 783 as 3² × 29 and missing all the key factors.
Factors of 783 Examples
Problem 1
There are 9 friends and 783 marbles. How will they divide them equally?
They will get 87 marbles each.
Explanation
To divide the marbles equally, we need to divide the total marbles by the number of friends.
783/9 = 87
Problem 2
An artist has a rectangular canvas, the length of the canvas is 29 inches and the total area is 783 square inches. Find the width.
27 inches.
Explanation
To find the width of the canvas, we use the formula,
Area = length × width
783 = 29 × width
To find the value of width, we need to divide 783 by 29.
783/29 = width
Width = 27.
Problem 3
There are 3 gift baskets and 783 chocolates. How many chocolates will be in each basket?
Each basket will have 261 chocolates.
Explanation
To find the chocolates in each basket, divide the total chocolates by the number of baskets.
783/3 = 261
Problem 4
In a class, there are 87 students, and 9 groups. How many students are there in each group?
There are 9 students in each group.
Explanation
Dividing the students by the total groups, we will get the number of students in each group.
87/9 = 9
Problem 5
783 books need to be arranged in 3 shelves. How many books will go on each shelf?
Each of the shelves has 261 books.
Explanation
Divide total books by shelves.
783/3 = 261
