Factors of 4.5
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 4.5, how they are used in real life, and tips to understand them quickly.
What are the Factors of 4.5?
The numbers that divide 4.5 evenly are known as factors of 4.5. A factor of 4.5 is a number that divides the number without remainder. The factors of 4.5 include numbers like 1.5 and 3, as they divide 4.5 without leaving a remainder. Negative factors of 4.5: -1.5 and -3. Prime factors of 4.5: 1.5 and 3. Prime factorization of 4.5: 1.5 × 3. The sum of factors of 4.5: 1.5 + 3 = 4.5
How to Find Factors of 4.5?
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 4.5. Identifying the numbers which are multiplied to get the number 4.5 is the multiplication method. Step 1: Multiply 3 by 1.5, 3 × 1.5 = 4.5. Therefore, the positive factor pairs of 4.5 are: (1.5, 3). All these factor pairs result in 4.5. 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 4.5 by 1.5, 4.5 ÷ 1.5 = 3. Step 2: Continue dividing 4.5 by the numbers until the remainder becomes 0. 4.5 ÷ 1.5 = 3 Therefore, the factors of 4.5 include: 1.5 and 3.
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 4.5 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1. 4.5 ÷ 1.5 = 3 The prime factors of 4.5 are 1.5 and 3. The prime factorization of 4.5 is: 1.5 × 3.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows - Step 1: Firstly, 4.5 is divided by 1.5 to get 3. Here, 3 is a prime number that cannot be divided anymore. So, the prime factorization of 4.5 is: 1.5 × 3. 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 4.5: (1.5, 3). Negative factor pairs of 4.5: (-1.5, -3).
Common Mistakes and How to Avoid Them in Factors of 4.5
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 4.5, 1.5 and 3 are also factors.
Factors of 4.5 Examples
Problem 1
There are 4.5 liters of juice and 1.5-liter bottles. How many bottles are needed to store all the juice?
3 bottles are needed.
Explanation
To store the juice equally, we need to divide the total liters by the capacity of each bottle. 4.5/1.5 = 3
Problem 2
A rectangle has an area of 4.5 square meters and the length is 3 meters. What is the width?
1.5 meters.
Explanation
To find the width of the rectangle, we use the formula, Area = length × width 4.5 = 3 × width To find the value of width, we need to shift 3 to the left side. 4.5/3 = width Width = 1.5.
Problem 3
There are 3 parcels, and the total weight is 4.5 kilograms. How much does each parcel weigh?
Each parcel weighs 1.5 kilograms.
Explanation
To find the weight of each parcel, divide the total weight by the number of parcels. 4.5/3 = 1.5
Problem 4
A group of 1.5 tables needs to accommodate 4.5 meters of tablecloth. How many meters of tablecloth should cover each table?
Each table should cover 3 meters of tablecloth.
Explanation
Dividing the total tablecloth by the number of tables, we will get the amount for each table. 4.5/1.5 = 3
Problem 5
4.5 liters of paint need to be used on 3 walls. How much paint will go on each wall?
Each wall will have 1.5 liters of paint.
Explanation
Divide total liters of paint by walls. 4.5/3 = 1.5
