The question asks for a factor pair of 5. A factor pair of a number consists of two integers that multiply together to give that number.

For 5, the factor pairs are:

1 × 5 = 5.

Thus, the answer for the blanks is:

• The first blank: 1
• The second blank: 5

Here are some related questions to deepen your understanding:

1. What are the factors of a prime number, and why?
2. How can we find factor pairs of larger numbers?
3. What is the difference between prime and composite numbers?
4. Can negative numbers be considered factors? Why or why not?
5. How is the concept of factorization used in real-life applications like engineering or finance?

Tip: Always start factorization by dividing the number by 1 and itself, as those are guaranteed factors.
