Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing the items equally, arranging things, etc. In this topic, we will learn about the factors of 680, how they are used in real life, and tips to learn them quickly.
The numbers that divide 680 evenly are known as factors of 680.
A factor of 680 is a number that divides the number without a remainder.
The factors of 680 are 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, and 680.
Negative factors of 680: -1, -2, -4, -5, -8, -10, -17, -20, -34, -40, -68, -85, -136, -170, -340, and -680.
Prime factors of 680: 2, 5, and 17.
Prime factorization of 680: (23 times 5 times 17).
The sum of factors of 680: 1 + 2 + 4 + 5 + 8 + 10 + 17 + 20 + 34 + 40 + 68 + 85 + 136 + 170 + 340 + 680 = 1620
Factors can be found using different methods. Mentioned below are some commonly used methods:
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 680. Identifying the numbers which are multiplied to get the number 680 is the multiplication method.
Step 1: Multiply 680 by 1, (680 times 1 = 680).
Step 2: Check for other numbers that give 680 after multiplying
(2 times 340 = 680)
(4 times 170 = 680)
(5 times 136 = 680)
(8 times 85 = 680)
(10 times 68 = 680)
(17 times 40 = 680)
(20 times 34 = 680)
Therefore, the positive factor pairs of 680 are: (1, 680), (2, 340), (4, 170), (5, 136), (8, 85), (10, 68), (17, 40), (20, 34). 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 which result as whole numbers as factors. Factors can be calculated by following a simple division method
Step 1: Divide 680 by 1, (680 div 1 = 680).
Step 2: Continue dividing 680 by the numbers until the remainder becomes 0.
(680 div 1 = 680)
(680 div 2 = 340)
(680 div 4 = 170)
(680 div 5 = 136)
(680 div 8 = 85)
(680 div 10 = 68)
(680 div 17 = 40)
(680 div 20 = 34)
Therefore, the factors of 680 are: 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680.
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 680 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
(680 div 2 = 340)
(340 div 2 = 170)
(170 div 2 = 85)
(85 div 5 = 17)
(17 div 17 = 1)
The prime factors of 680 are 2, 5, and 17.
The prime factorization of 680 is: (23 times 5 times 17).
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 680 is divided by 2 to get 340.
Step 2: Now divide 340 by 2 to get 170.
Step 3: Then divide 170 by 2 to get 85.
Step 4: Divide 85 by 5 to get 17. Here, 17 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 680 is: (23 times 5 times 17).
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 680: (1, 680), (2, 340), (4, 170), (5, 136), (8, 85), (10, 68), (17, 40), (20, 34).
Negative factor pairs of 680: (-1, -680), (-2, -340), (-4, -170), (-5, -136), (-8, -85), (-10, -68), (-17, -40), (-20, -34).
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
There are 68 people and 680 apples. How will they divide them equally?
They will get 10 apples each.
To divide the apples equally, we need to divide the total apples by the number of people.
(680 div 68 = 10)
A rectangular garden has a length of 34 meters and a total area of 680 square meters. Find the width.
20 meters.
To find the width of the garden, we use the formula, Area = length × width
(680 = 34 times text{width})
To find the value of width, we need to shift 34 to the left side.
(680 div 34 = text{width})
Width = 20.
There are 136 containers and 680 liters of water. How many liters will be in each container?
Each container will have 5 liters.
To find the volume in each container, divide the total liters by the number of containers.
(680 div 136 = 5)
In a workshop, there are 680 tools, and 10 sections. How many tools are there in each section?
There are 68 tools in each section.
Dividing the tools by the total sections, we will get the number of tools in each section.
(680 div 10 = 68)
680 chairs need to be arranged in 17 rows. How many chairs will go in each row?
Each row has 40 chairs.
Divide the total chairs by the number of rows.
(680 div 17 = 40)
