How to Find Factors of 3100?
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 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.
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 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.
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 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.
Factor Tree
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).
Common Mistakes and How to Avoid Them in Factors of 3100
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 3100, 1 and 3100 are also factors.
Mistake 2
Missing Negative Factors
We often mention only positive factors. There are also negative factors, so always check whether you have mentioned negative factors.
For example, the factors of 3100 include -1, -2, -4, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions as factors. Only whole numbers can be factors.
For example, thinking 1.5 as a factor, because 3100/1.5 = 2066.667, 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 3100 are prime numbers.
For example, 2, 5, and 31 are the prime factors of 3100, but it has other factors like 4, 10.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 3100 as 2 × 2 × 5 × 5 × 31 and missing all the key factors.
Factors of 3100 Examples
Problem 1
There are 62 friends and 3100 apples. How will they divide it equally?
They will get 50 apples each.
Explanation
To divide the apples equally, we need to divide the total apples by the number of friends.
3100/62 = 50
Problem 2
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.
Explanation
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.
