Question

Write 2 numbers, neither of which is 8, whose greatest common factor (GCF) is 8.

A. Various number pairs with GCF of 8.
B. Number pairs with GCF other than 8.
C. No GCF questions.
D. A mix of GCF questions and non-GCF questions.

Answer 1

Two numbers that have a GCF of 8 and are not the number 8 are 16 and 24. These numbers are examples of multiples of 8, which is the GCF we are looking for. To identify numbers with a specific GCF, it's helpful to think of the GCF's multiples.

Step-by-step explanation:

To write 2 numbers, neither of which is 8, whose greatest common factor (GCF) is 8, you need to think of multiples of 8 that are not the number 8 itself. For example, 16 and 24 both have a GCF of 8. Here's a step-by-step explanation:

1. Identify the GCF in question, which is 8 in this case.
2. Think of multiples of 8. Some of the multiples of 8 are 16, 24, 32, and so on (excluding the number 8 itself).
3. Select any two multiples of 8 (other than 8 itself). Let's take 16 and 24.
4. Verify that the GCF is indeed 8. We know that 16 = 2 * 8 and 24 = 3 * 8. Since both numbers are made by multiplying 8 by an integer, the only common factor they share besides 1 is 8.

Therefore, the two numbers that have a GCF of 8 and are not the number 8 are 16 and 24.
