Prime factorization of 1340: 22 × 5 × 67.
The sum of factors of 1340: 1 + 2 + 4 + 5 + 10 + 20 + 67 + 134 + 268 + 335 + 670 + 1340 = 2856
How to Find Factors of 1340?
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 1340. Identifying the numbers which are multiplied to get the number 1340 is the multiplication method.
Step 1: Multiply 1340 by 1, 1340 × 1 = 1340.
Step 2: Check for other numbers that give 1340 after multiplying
2 × 670 = 1340
4 × 335 = 1340
5 × 268 = 1340
10 × 134 = 1340
20 × 67 = 1340
Therefore, the positive factor pairs of 1340 are: (1, 1340), (2, 670), (4, 335), (5, 268), (10, 134), (20, 67).
For every positive factor, there is a negative factor.
Finding Factors Using Division Method
Dividing the given numbers with 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 1340 by 1, 1340 ÷ 1 = 1340.
Step 2: Continue dividing 1340 by the numbers until the remainder becomes 0.
1340 ÷ 1 = 1340
1340 ÷ 2 = 670
1340 ÷ 4 = 335
1340 ÷ 5 = 268
1340 ÷ 10 = 134
1340 ÷ 20 = 67
Therefore, the factors of 1340 are: 1, 2, 4, 5, 10, 20, 67, 134, 268, 335, 670, 1340.
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 1340 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1340 ÷ 2 = 670
670 ÷ 2 = 335
335 ÷ 5 = 67
67 is a prime number, so the division stops here.
The prime factors of 1340 are 2, 5, and 67.
The prime factorization of 1340 is: 2^2 × 5 × 67.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows:
Step 1: Firstly, 1340 is divided by 2 to get 670.
Step 2: Now divide 670 by 2 to get 335.
Step 3: Then divide 335 by 5 to get 67. 67 is a prime number, so the division stops here. So, the prime factorization of 1340 is: 22 × 5 × 67.
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 1340: (1, 1340), (2, 670), (4, 335), (5, 268), (10, 134), and (20, 67).
Negative factor pairs of 1340: (-1, -1340), (-2, -670), (-4, -335), (-5, -268), (-10, -134), and (-20, -67).
Common Mistakes and How to Avoid Them in Factors of 1340
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 1340, 1 and 1340 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 1340 consist of -1, -2, -4, etc.
Mistake 3
Including the Fraction
Children might sometimes add a fraction also as a factor. Only whole numbers can be a factor.
For example, thinking 3.5 as a factor, because 1340/3.5 = 382.857, 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 1340 are prime numbers.
For example, 2, 5, and 67 are the prime factors of 1340, but it has other factors like 10, 20.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 1340 as 22 × 5 × 67 and missing all the key factors.
Factors of 1340 Examples
Problem 1
There are 20 friends and 1340 marbles. How will they divide it equally?
They will get 67 marbles each.
Explanation
To divide the marbles equally, we need to divide the total marbles with the number of friends.
1340/20 = 67
Problem 2
A garden is rectangular, the length of the garden is 10 meters and the total area is 1340 square meters. Find the width?
134 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
1340 = 10 × width
To find the value of width, we need to shift 10 to the left side.
1340/10 = width
Width = 134.
