It seems you're referring to one of the potential questions I listed, specifically:

**"How can the Euclidean algorithm be used to find the GCD of 13 and 18?"**

Let's solve this using the Euclidean algorithm:

### Steps to find the GCD using the Euclidean Algorithm:
1. **Divide the larger number by the smaller number** and find the remainder.
2. **Replace the larger number with the smaller number**, and the smaller number with the remainder from the previous step.
3. **Repeat this process** until the remainder is 0.
4. The last non-zero remainder is the **GCD**.

### Applying it to 13 and 18:
1. **Step 1:** Divide 18 by 13:
   \[
   18 \div 13 = 1 \text{ remainder } 5
   \]
2. **Step 2:** Now, replace 18 with 13 and 13 with 5, and repeat the process:
   \[
   13 \div 5 = 2 \text{ remainder } 3
   \]
3. **Step 3:** Replace 13 with 5 and 5 with 3, and repeat the process:
   \[
   5 \div 3 = 1 \text{ remainder } 2
   \]
4. **Step 4:** Replace 5 with 3 and 3 with 2, and repeat the process:
   \[
   3 \div 2 = 1 \text{ remainder } 1
   \]
5. **Step 5:** Replace 3 with 2 and 2 with 1, and repeat the process:
   \[
   2 \div 1 = 2 \text{ remainder } 0
   \]

Since the remainder is now 0, the last non-zero remainder is **1**.

### Final Answer:
The **GCD of 13 and 18 is 1**.
