The first three-digit natural number divisible by 7 is 105.
According to the provided reference, "Hence 105 is the smallest 3 digit number that is divisible by 7." This statement directly answers the question.
Here's a breakdown of how we arrive at this:
- The smallest three-digit number is 100.
- We need to find the first multiple of 7 that is greater than or equal to 100.
- Dividing 100 by 7 gives us approximately 14.28.
- This means that 14 7 = 98 (which is less than 100) and 15 7 is the next multiple of 7.
- 15 * 7 = 105
Therefore:
| Calculation | Result |
|---|---|
| 100 / 7 | 14.28 |
| 14 * 7 | 98 |
| 15 * 7 | 105 |
Thus, 105 is the first three-digit number divisible by 7.
