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 3100, how they are used in real life, and tips to learn them quickly.
The numbers that divide 3100 evenly are known as factors of 3100.
A factor of 3100 is a number that divides the number without remainder.
The factors of 3100 are 1, 2, 4, 5, 10, 20, 31, 50, 62, 100, 124, 155, 310, 620, 775, 1550, and 3100.
Negative factors of 3100: -1, -2, -4, -5, -10, -20, -31, -50, -62, -100, -124, -155, -310, -620, -775, -1550, -3100.
Prime factors of 3100: 2, 5, and 31.
Prime factorization of 3100: 2 × 2 × 5 × 5 × 31.
The sum of factors of 3100: 1 + 2 + 4 + 5 + 10 + 20 + 31 + 50 + 62 + 100 + 124 + 155 + 310 + 620 + 775 + 1550 + 3100 = 6924
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 3100. Identifying the numbers which are multiplied to get the number 3100 is the multiplication method.
Step 1: Multiply 3100 by 1, 3100 × 1 = 3100.
Step 2: Check for other numbers that give 3100 after multiplying
2 × 1550 = 3100
4 × 775 = 3100
5 × 620 = 3100
10 × 310 = 3100
20 × 155 = 3100
31 × 100 = 3100
50 × 62 = 3100
Therefore, the positive factor pairs of 3100 are: (1, 3100), (2, 1550), (4, 775), (5, 620), (10, 310), (20, 155), (31, 100), (50, 62). 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 3100 by 1, 3100 ÷ 1 = 3100.
Step 2: Continue dividing 3100 by the numbers until the remainder becomes 0.
3100 ÷ 1 = 3100
3100 ÷ 2 = 1550
3100 ÷ 4 = 775
3100 ÷ 5 = 620
3100 ÷ 10 = 310
3100 ÷ 20 = 155
3100 ÷ 31 = 100
3100 ÷ 50 = 62
Therefore, the factors of 3100 are: 1, 2, 4, 5, 10, 20, 31, 50, 62, 100, 124, 155, 310, 620, 775, 1550, 3100.
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 3100 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
3100 ÷ 2 = 1550
1550 ÷ 2 = 775
775 ÷ 5 = 155
155 ÷ 5 = 31
31 ÷ 31 = 1
The prime factors of 3100 are 2, 5, and 31.
The prime factorization of 3100 is: 2 × 2 × 5 × 5 × 31.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 3100 is divided by 2 to get 1550.
Step 2: Now divide 1550 by 2 to get 775.
Step 3: Then divide 775 by 5 to get 155.
Step 4: Divide 155 by 5 to get 31. Here, 31 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 3100 is: 2 × 2 × 5 × 5 × 31.
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 3100: (1, 3100), (2, 1550), (4, 775), (5, 620), (10, 310), (20, 155), (31, 100), (50, 62).
Negative factor pairs of 3100: (-1, -3100), (-2, -1550), (-4, -775), (-5, -620), (-10, -310), (-20, -155), (-31, -100), (-50, -62).
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 62 friends and 3100 apples. How will they divide it equally?
They will get 50 apples each.
To divide the apples equally, we need to divide the total apples by the number of friends.
3100/62 = 50
A field is rectangular, the length of the field is 31 meters, and the total area is 3100 square meters. Find the width.
100 meters.
To find the width of the field, we use the formula,
Area = length × width
3100 = 31 × width
To find the value of width, we need to shift 31 to the left side.
3100/31 = width
Width = 100.
There are 155 bags and 3100 candies. How many candies will be in each bag?
Each bag will have 20 candies.
To find the candies in each bag, divide the total candies by the bags.
3100/155 = 20
In a class, there are 3100 students and 62 groups. How many students are there in each group?
There are 50 students in each group.
Dividing the students by the total groups, we will get the number of students in each group.
3100/62 = 50
3100 books need to be arranged in 155 shelves. How many books will go on each shelf?
Each of the shelves has 20 books.
Divide total books by shelves. 3100/155 = 20
