Factors of 1420
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 1420, how they are used in real life, and tips to learn them quickly.
What are the Factors of 1420?
The numbers that divide 1420 evenly are known as factors of 1420.
A factor of 1420 is a number that divides the number without remainder.
The factors of 1420 are 1, 2, 4, 5, 10, 20, 71, 142, 284, 355, 710, and 1420.
Negative factors of 1420: -1, -2, -4, -5, -10, -20, -71, -142, -284, -355, -710, and -1420.
Prime factors of 1420: 2, 5, and 71.
Prime factorization of 1420: 22 × 5 × 71.
The sum of factors of 1420: 1 + 2 + 4 + 5 + 10 + 20 + 71 + 142 + 284 + 355 + 710 + 1420 = 3024
How to Find Factors of 1420?
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 1420. Identifying the numbers which are multiplied to get the number 1420 is the multiplication method.
Step 1: Multiply 1420 by 1, 1420 × 1 = 1420.
Step 2: Check for other numbers that give 1420 after multiplying
2 × 710 = 1420
4 × 355 = 1420
5 × 284 = 1420
10 × 142 = 1420
20 × 71 = 1420
Therefore, the positive factor pairs of 1420 are: (1, 1420), (2, 710), (4, 355), (5, 284), (10, 142), (20, 71).
All these factor pairs result in 1420.
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 1420 by 1, 1420 ÷ 1 = 1420.
Step 2: Continue dividing 1420 by the numbers until the remainder becomes 0.
1420 ÷ 1 = 1420
1420 ÷ 2 = 710
1420 ÷ 4 = 355
1420 ÷ 5 = 284
1420 ÷ 10 = 142
1420 ÷ 20 = 71
Therefore, the factors of 1420 are: 1, 2, 4, 5, 10, 20, 71, 142, 284, 355, 710, 1420.
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 1420 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1420 ÷ 2 = 710
710 ÷ 2 = 355
355 ÷ 5 = 71
71 ÷ 71 = 1
The prime factors of 1420 are 2, 5, and 71. The prime factorization of 1420 is: 22 × 5 × 71.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1420 is divided by 2 to get 710.
Step 2: Now divide 710 by 2 to get 355.
Step 3: Then divide 355 by 5 to get 71. Here, 71 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 1420 is: 22 × 5 × 71.
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 1420: (1, 1420), (2, 710), (4, 355), (5, 284), (10, 142), and (20, 71).
Negative factor pairs of 1420: (-1, -1420), (-2, -710), (-4, -355), (-5, -284), (-10, -142), and (-20, -71).
Common Mistakes and How to Avoid Them in Factors of 1420
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 word. Always remember to include 1 and the number itself.
For example, in factors of 1420, 1 and 1420 is also a factor.
Factors of 1420 Examples
Problem 1
There are 10 people and 1420 marbles. How will they divide it equally?
They will get 142 marbles each.
Explanation
To divide the marbles equally, we need to divide the total marbles with the number of people.
1420/10 = 142
Problem 2
A wall is 20 meters long and has a total area of 1420 square meters. Find the height of the wall.
71 meters.
Explanation
To find the height of the wall, we use the formula,
Area = length × height
1420 = 20 × height
To find the value of height, we need to shift 20 to the left side.
1420/20 = height
Height = 71.
Problem 3
There are 142 bags and 1420 candies. How many candies will be in each bag?
Each bag will have 10 candies.
Explanation
To find the candies in each bag, divide the total candies with the bags.
1420/142 = 10
Problem 4
In a class, there are 355 students, and 5 groups. How many students are there in each group?
There are 71 students in each group.
Explanation
Dividing the students with the total groups, we will get the number of students in each group.
355/5 = 71
Problem 5
1420 books need to be arranged in 71 shelves. How many books will go on each shelf?
Each of the shelves has 20 books.
Explanation
Divide total books with shelves.
1420/71 = 20
