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 278, how they are used in real life, and the tips to learn them quickly.
The numbers that divide 278 evenly are known as factors of 278.
A factor of 278 is a number that divides the number without a remainder.
The factors of 278 are 1, 2, 139, and 278.
Negative factors of 278: -1, -2, -139, and -278.
Prime factors of 278: 2 and 139.
Prime factorization of 278: 2 × 139.
The sum of factors of 278: 1 + 2 + 139 + 278 = 420
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 278. Identifying the numbers which are multiplied to get the number 278 is the multiplication method.
Step 1: Multiply 278 by 1, 278 × 1 = 278.
Step 2: Check for other numbers that give 278 after multiplying 2 × 139 = 278
Therefore, the positive factor pairs of 278 are: (1, 278) and (2, 139).
All these factor pairs result in 278.
For every positive factor, there is a negative factor.
Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which result as a whole number as factors. Factors can be calculated by following a simple division method
Step 1: Divide 278 by 1, 278 ÷ 1 = 278.
Step 2: Continue dividing 278 by the numbers until the remainder becomes 0.
278 ÷ 1 = 278
278 ÷ 2 = 139
Therefore, the factors of 278 are: 1, 2, 139, 278.
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 278 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
278 ÷ 2 = 139
139 ÷ 139 = 1
The prime factors of 278 are 2 and 139. The prime factorization of 278 is: 2 × 139.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 278 is divided by 2 to get 139. Here, 139 is a prime number that cannot be divided anymore. So, the prime factorization of 278 is: 2 × 139.
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 278: (1, 278), (2, 139).
Negative factor pairs of 278: (-1, -278), (-2, -139).
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
A farmer has 278 apples and wants to pack them into boxes with each box containing 2 apples. How many boxes will he need?
He will need 139 boxes.
To find out the number of boxes needed, divide the total apples by the number in each box.
278/2 = 139
A rectangular field has an area of 278 square meters, and its width is 2 meters. What is the length of the field?
139 meters.
To find the length of the field, we use the formula,
Area = length × width
278 = length × 2
To find the value of length, divide the area by the width.
278/2 = length
Length = 139.
There are 278 students in a school, and each bus can carry 139 students. How many buses are needed?
2 buses are needed.
To find the number of buses needed, divide the total students by the capacity of each bus.
278/139 = 2
A company has 278 units of a product and wants to distribute them equally in 2 warehouses. How many units will each warehouse receive?
Each warehouse will receive 139 units.
Dividing the total units by the number of warehouses gives us the number of units per warehouse.
278/2 = 139
278 books need to be arranged evenly across 2 shelves. How many books will go on each shelf?
Each of the shelves will have 139 books.
Divide the total books by the number of shelves.
278/2 = 139
