Introduction

In mathematics, factor pairs are the combinations of two numbers that multiply together to give a specific product. In this article, we will focus on finding the factor pairs of the number 42. We will use the given numbers: 4, 7, 21, 3, 5, and 13 to complete the table and explore the concept of factor pairs in detail.

What are Factor Pairs?

Factor pairs are the combinations of two numbers that multiply together to give a specific product. For example, the factor pairs of 12 are (1, 12), (2, 6), and (3, 4). These pairs are also known as factors or divisors of the number.

Finding Factor Pairs of 42

To find the factor pairs of 42, we need to identify all the combinations of two numbers that multiply together to give 42. We will use the given numbers: 4, 7, 21, 3, 5, and 13 to complete the table.

Step 1: List the Given Numbers

Step 2: Find the Factor Pairs

To find the factor pairs, we need to multiply each number with every other number to see if the product is equal to 42.

First Factor	Second Factor
1	42
2	21
3	14
4	10.5
5	8.4
6	7
7	6
8	5.25
10	4.2
12	3.5
14	3
15	2.8
18	2.33
21	2
28	1.5
30	1.4
42	1

Step 3: Identify the Correct Factor Pairs

From the table above, we can see that the correct factor pairs of 42 are:

(1, 42)
(2, 21)
(3, 14)
(6, 7)

Discussion

In this article, we have explored the concept of factor pairs and found the factor pairs of the number 42. We have used the given numbers: 4, 7, 21, 3, 5, and 13 to complete the table and identify the correct factor pairs.

Conclusion

In conclusion, factor pairs are an essential concept in mathematics that helps us understand the properties of numbers. By finding the factor pairs of a number, we can gain insights into its properties and behavior. In this article, we have found the factor pairs of the number 42 and explored the concept of factor pairs in detail.
