The number 40 is divisible by both 8 and 5.
The reference provided states that since the factors of 8 (1, 2, 4, and 8) and 5 (1 and 5) have a greatest common factor of 1, the two numbers are considered co-prime. Therefore, a number divisible by both 8 and 5 will also be divisible by their product.
The product of 8 and 5 is 40 (8 x 5 = 40). As stated in the reference, dividing 40 by 5 yields 8, and dividing 40 by 8 yields 5, confirming that 40 is divisible by both 5 and 8.
Here's a table showing the divisibility:
| Number | Divisible by 8? | Divisible by 5? |
|---|---|---|
| 40 | Yes (40 / 8 = 5) | Yes (40 / 5 = 8) |
Therefore, 40 is the smallest positive number divisible by both 8 and 5, and any multiple of 40 (80, 120, 160, etc.) will also be divisible by 8 and 5.
