Answer 1

To list the factors of the provided numbers, we need to find the numbers that can divide each of them without leaving a remainder. Note that factors are typically whole numbers, so for decimal and fractional numbers, we will list their factors as if they were whole numbers.

1. **11.36**:
- Since 11.36 can be treated as 1136 (after multiplying by 100 to eliminate the decimal), the factors of 1136 are:
- Factors: 1, 2, 4, 8, 142, 284, 568, 1136

2. **13.45**:
- As a decimal, we can consider it as 1345. The factors of 1345 are:
- Factors: 1, 5, 269, 1345

3. **15.125**:
- Similar approach; treating it as 15125, the factors are:
- Factors: 1, 5, 25, 605, 3025, 15125

4. **17.16**:
- Treating it as 1716, the factors of 1716 are:
- Factors: 1, 2, 3, 4, 6, 12, 143, 238, 429, 858, 1716

5. **12.29**:
- For 12.29, treating it as 1229 gives us:
- Factors: 1, 1229 (Note: 1229 is a prime number)

6. **14.81**:
- As an integer: 1481, which is also prime, gives us:
- Factors: 1, 1481

7. **16.117**:
- Treating as 16117, the factors of 16117 are:
- Factors: 1, 16117 (Note: 16117 is also a prime number)

8. **18.69**:
- As an integer, 1869 has the following factors:
- Factors: 1, 3, 623, 1869

### Summary of factors:
- 11.36: 1, 2, 4, 8, 142, 284, 568, 1136
- 13.45: 1, 5, 269, 1345
- 15.125: 1, 5, 25, 605, 3025, 15125
- 17.16: 1, 2, 3, 4, 6, 12, 143, 238, 429, 858, 1716
