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 1405, how they are used in real life, and tips to learn them quickly.
The numbers that divide 1405 evenly are known as factors of 1405.
A factor of 1405 is a number that divides the number without remainder.
The factors of 1405 are 1, 5, 281, and 1405.
Negative factors of 1405: -1, -5, -281, and -1405.
Prime factors of 1405: 5 and 281.
Prime factorization of 1405: 5 × 281.
The sum of factors of 1405: 1 + 5 + 281 + 1405 = 1692
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 1405. Identifying the numbers which are multiplied to get the number 1405 is the multiplication method.
Step 1: Multiply 1405 by 1, 1405 × 1 = 1405.
Step 2: Check for other numbers that give 1405 after multiplying
5 × 281 = 1405
Therefore, the positive factor pairs of 1405 are: (1, 1405), (5, 281).
For every positive factor, there is a negative factor.
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 1405 by 1, 1405 ÷ 1 = 1405.
Step 2: Continue dividing 1405 by the numbers until the remainder becomes 0.
1405 ÷ 1 = 1405
1405 ÷ 5 = 281
Therefore, the factors of 1405 are: 1, 5, 281, 1405.
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 1405 divide the number to break it down in the multiplication form of prime factors until the remainder becomes 1.
1405 ÷ 5 = 281
281 ÷ 281 = 1
The prime factors of 1405 are 5 and 281.
The prime factorization of 1405 is: 5 × 281.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1405 is divided by 5 to get 281.
Step 2: Now divide 281 by 281 to get 1. Here, 281 is a prime number and cannot be divided further.
So, the prime factorization of 1405 is: 5 × 281.
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 1405: (1, 1405), (5, 281).
Negative factor pairs of 1405: (-1, -1405), (-5, -281).
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 5 cars and 1405 miles to travel. How far will each car travel if they travel equally?
Each car will travel 281 miles.
To divide the total miles equally, we need to divide the total miles by the number of cars.
1405/5 = 281
A concert hall has 1405 seats, and each row has 281 seats. How many rows are there?
There are 5 rows.
To find the number of rows, we use the formula,
Total seats = number of rows × seats per row
1405 = number of rows × 281
To find the number of rows, divide 1405 by 281.
1405/281 = number of rows
Number of rows = 5.
There are 281 trees and 1405 apples. How many apples are on each tree?
Each tree has 5 apples.
To find the apples on each tree, divide the total apples by the number of trees.
1405/281 = 5
A library has 1405 books and 5 sections. How many books are in each section?
There are 281 books in each section.
Dividing the books by the total sections, we will get the number of books in each section.
1405/5 = 281
1405 pages need to be printed in 5 days. How many pages will be printed each day?
Each day, 281 pages will be printed.
Divide total pages by the number of days.
1405/5 = 281
