What are the Factors of 1580?
The numbers that divide 1580 evenly are known as factors of 1580.
A factor of 1580 is a number that divides the number without a remainder.
The factors of 1580 are 1, 2, 5, 10, 79, 158, 395, 790, and 1580.
Negative factors of 1580: -1, -2, -5, -10, -79, -158, -395, -790, and -1580.
Prime factors of 1580: 2, 5, and 79.
Prime factorization of 1580: 2 × 5 × 79.
The sum of factors of 1580: 1 + 2 + 5 + 10 + 79 + 158 + 395 + 790 + 1580 = 3020
How to Find Factors of 1580?
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 1580. Identifying the numbers which are multiplied to get the number 1580 is the multiplication method.
Step 1: Multiply 1580 by 1, 1580 × 1 = 1580.
Step 2: Check for other numbers that give 1580 after multiplying:
2 × 790 = 1580
5 × 316 = 1580
10 × 158 = 1580
79 × 20 = 1580
Therefore, the positive factor pairs of 1580 are: (1, 1580), (2, 790), (5, 316), (10, 158), and (79, 20).
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 1580 by 1, 1580 ÷ 1 = 1580.
Step 2: Continue dividing 1580 by the numbers until the remainder becomes 0.
1580 ÷ 1 = 1580
1580 ÷ 2 = 790
1580 ÷ 5 = 316
1580 ÷ 10 = 158
1580 ÷ 79 = 20
Therefore, the factors of 1580 are: 1, 2, 5, 10, 79, 158, 395, 790, 1580.
Prime Factors and Prime Factorization
The factors can be found by dividing them 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 1580 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1580 ÷ 2 = 790
790 ÷ 5 = 158
158 ÷ 79 = 2
2 ÷ 2 = 1
The prime factors of 1580 are 2, 5, and 79.
The prime factorization of 1580 is: 2 × 5 × 79.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows:
Step 1: Firstly, 1580 is divided by 2 to get 790.
Step 2: Now divide 790 by 5 to get 158.
Step 3: Then divide 158 by 79 to get 2.
Step 4: Divide 2 by 2 to get 1.
The prime factorization of 1580 is: 2 × 5 × 79.
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 1580: (1, 1580), (2, 790), (5, 316), (10, 158), and (79, 20).
Negative factor pairs of 1580: (-1, -1580), (-2, -790), (-5, -316), (-10, -158), and (-79, -20).
Common Mistakes and How to Avoid Them in Factors of 1580
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 1580, 1 and 1580 are also factors.
Mistake 2
Missing Negative Factors
We often mention only positive factors every time. There are also negative factors, always check whether you have mentioned negative factors.
For example, the factors of 1580 include -1, -2, -5, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions also as factors. Only whole numbers can be factors.
For example, thinking 1.5 as a factor, because 1580/1.5 = 1053.333, 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 1580 are prime numbers.
For example, 2, 5, and 79 are the prime factors of 1580, but it has other factors like 10 and 158.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 1580 as 2 × 5 × 79 and missing all the key factors.
Factors of 1580 Examples
Problem 1
There are 5 teams and 1580 badges. How will they distribute them equally?
They will get 316 badges each.
Explanation
To distribute the badges equally, divide the total badges by the number of teams.
1580/5 = 316
Problem 2
A rectangular park has a length of 79 meters and a total area of 1580 square meters. Find the width.
20 meters.
Explanation
To find the width of the park, use the formula:
Area = length × width
1580 = 79 × width
To find the value of width, divide 1580 by 79.
1580/79 = width
Width = 20.
Problem 3
There are 1580 candies and 10 bags. How many candies will be in each bag?
Each bag will have 158 candies.
Explanation
To find the candies in each bag, divide the total candies by the number of bags. 1580/10 = 158
Problem 4
In a class, there are 1580 students, and 395 groups. How many students are there in each group?
There are 4 students in each group.
Explanation
Dividing the students by the total groups, we will get the number of students in each group.
1580/395 = 4
Problem 5
1580 books need to be arranged in 2 shelves. How many books will go on each shelf?
Each of the shelves has 790 books.
Explanation
Divide total books by shelves.
1580/2 = 790
