- Predecessor = 10,000 - 1
- Predecessor = 9,999

3. **Find the predecessor of 36,900**:
- Predecessor = 36,900 - 1
- Predecessor = 36,899

4. **Find the predecessor of 7,684,320**:
- Predecessor = 7,684,320 - 1
- Predecessor = 7,684,319

5. **Find the predecessor of 2,456,800**:
- Predecessor = 2,456,800 - 1
- Predecessor = 2,456,799

6. **Find the predecessor of 100,000**:
- Predecessor = 100,000 - 1
- Predecessor = 99,999

7. **Find the predecessor of 1,000,000**:
- Predecessor = 1,000,000 - 1
