What is the divisibility rule of 7?
Divisibility rules for numbers 1–30
| Divisor | Divisibility condition | Examples |
|---|---|---|
| 7 | Subtracting 2 times the last digit from the rest gives a multiple of 7. (Works because 21 is divisible by 7.) | 483: 48 − (3 × 2) = 42 = 7 × 6. |
| Subtracting 9 times the last digit from the rest gives a multiple of 7. | 483: 48 − (3 × 9) = 21 = 7 × 3. |
