Oct 13, 2025 by wbrum.org 3 views

Introduction

In mathematics, a multiple of a number is the product of that number and an integer. In other words, if we multiply a number by an integer, the result is a multiple of that number. In this article, we will explore which of the given numbers is a multiple of 4.

What is a Multiple of 4?

A multiple of 4 is a number that can be divided by 4 without leaving a remainder. In other words, if a number is a multiple of 4, it can be expressed as 4 multiplied by an integer. For example, 8, 12, 16, and 20 are all multiples of 4 because they can be divided by 4 without leaving a remainder.

How to Check if a Number is a Multiple of 4

To check if a number is a multiple of 4, we can use the following method:

Divide the number by 4.
If the result is an integer, then the number is a multiple of 4.
If the result is not an integer, then the number is not a multiple of 4.

Applying the Method to the Given Numbers

Now, let's apply the method to the given numbers:

A. 22

To check if 22 is a multiple of 4, we can divide it by 4:

22 ÷ 4 = 5.5

Since the result is not an integer, 22 is not a multiple of 4.

B. 32

To check if 32 is a multiple of 4, we can divide it by 4:

32 ÷ 4 = 8

Since the result is an integer, 32 is a multiple of 4.

C. 46

To check if 46 is a multiple of 4, we can divide it by 4:

46 ÷ 4 = 11.5

Since the result is not an integer, 46 is not a multiple of 4.

D. 14

To check if 14 is a multiple of 4, we can divide it by 4:

14 ÷ 4 = 3.5

Since the result is not an integer, 14 is not a multiple of 4.

Conclusion

In conclusion, the only number that is a multiple of 4 among the given options is 32. This is because 32 can be divided by 4 without leaving a remainder, making it a multiple of 4.

Final Answer

The final answer is B. 32.

Additional Tips and Tricks

Here are some additional tips and tricks to help you identify multiples of 4:

If a number ends in 0, 2, 4, 6, or 8, it is a multiple of 4.
If a number is even and can be divided by 2 without leaving a remainder, it is a multiple of 4.
If a number is a multiple of 2 and can be divided by 2 without leaving a remainder, it is a multiple of 4.

Introduction

In our previous article, we discussed what multiples of 4 are and how to check if a number is a multiple of 4. In this article, we will answer some frequently asked questions (FAQs) about multiples of 4.

Q: What is the difference between a multiple of 4 and a multiple of 2?

A: A multiple of 2 is a number that can be divided by 2 without leaving a remainder. A multiple of 4 is a number that can be divided by 4 without leaving a remainder. For example, 6 is a multiple of 2, but it is not a multiple of 4. On the other hand, 8 is a multiple of both 2 and 4.

Q: How can I find the multiples of 4 between two numbers?

A: To find the multiples of 4 between two numbers, you can use the following method:

Divide the larger number by 4 and round down to the nearest whole number.
Multiply the result by 4 to get the first multiple of 4.
Add 4 to the result to get the next multiple of 4.
Repeat step 3 until you reach the smaller number.

Q: What is the formula for finding the nth multiple of 4?

A: The formula for finding the nth multiple of 4 is:

Multiple of 4 = 4n

where n is the position of the multiple of 4.

Q: How can I check if a number is a multiple of 4 using a calculator?

A: To check if a number is a multiple of 4 using a calculator, you can divide the number by 4 and check if the result is an integer. If the result is an integer, then the number is a multiple of 4.

Q: What is the relationship between multiples of 4 and even numbers?

A: All multiples of 4 are even numbers, but not all even numbers are multiples of 4. For example, 6 is an even number, but it is not a multiple of 4.

Q: Can a number be a multiple of both 4 and another number?

A: Yes, a number can be a multiple of both 4 and another number. For example, 8 is a multiple of both 4 and 2.

Q: How can I find the least common multiple (LCM) of two numbers that are multiples of 4?

A: To find the LCM of two numbers that are multiples of 4, you can use the following method:

Find the prime factorization of each number.
Identify the common factors and multiply them together.
Multiply the result by the remaining factors to get the LCM.

Conclusion

In conclusion, multiples of 4 are an important concept in mathematics, and understanding them can help you solve a wide range of problems. By following the tips and tricks in this article, you can become more confident in your ability to identify multiples of 4 and solve problems involving them.
