Table of Contents :
To determine what multiplication equals 49, we need to explore the factors of the number 49. Factors are whole numbers that can be multiplied together to produce another number, in this case, 49. Understanding the factors of 49 can deepen your appreciation for multiplication and the relationships between numbers. Let’s dive into the world of factors and see how multiplication gives us 49! 📚
Understanding Factors
Before we get into the specifics of the number 49, let’s break down what factors are and how they work.
What Are Factors?
Factors are numbers you can multiply together to get another number. For example, in the multiplication equation (3 \times 4 = 12), both 3 and 4 are factors of 12. Every integer has a unique set of factors, including itself and one.
Why Are Factors Important?
Understanding factors is fundamental in various areas of mathematics. They are essential in:
- Simplifying Fractions: Factors can help reduce fractions to their simplest form.
- Finding Common Denominators: Understanding the factors of numbers aids in adding and subtracting fractions.
- Solving Equations: Recognizing factors can make it easier to solve multiplication equations.
Factors of 49
Now, let’s find out what multiplication equals 49 by identifying its factors!
The Prime Factorization of 49
To find the factors of 49, we can start with its prime factorization. Prime factorization is when a number is expressed as the product of its prime factors.
For 49, we can perform the following steps:
- 49 is an odd number, so it cannot be divided by 2.
- The next prime number is 3, but since (49 ÷ 3) doesn’t give a whole number, we move to the next prime number, which is 5.
- Finally, we try 7: (49 ÷ 7 = 7).
So, the prime factorization of 49 is:
[ 49 = 7 \times 7 \quad \text{(or)} \quad 49 = 7^2 ]
From this, we can see that 7 is the only prime factor of 49.
List of Factors of 49
Let’s compile a complete list of the factors of 49. This includes all whole numbers that can multiply in pairs to give 49.
The factors of 49 are:
- 1
- 7
- 49
To put it simply:
<table> <tr> <th>Factor Pair</th> <th>Multiplication Result</th> </tr> <tr> <td>1 × 49</td> <td>49</td> </tr> <tr> <td>7 × 7</td> <td>49</td> </tr> </table>
Understanding the Factor Pairs
From the table above, we can see that:
- 1 and 49 are factors. When multiplied together, they yield 49.
- 7 multiplied by itself (7 × 7) also yields 49, showcasing that 7 is a perfect square factor of 49.
