Find the greatest positive integer $n$ for which $n$ is divisible by all positive integers whose cube is not greater than $n.$
To find the greatest positive integer \( n \) for which \( n \) is divisible by all positive integers whose cube is not greater than \( n \), we need to consider the cubes of integers and their relationship to \( n \).

1. **Identify the range of integers whose cubes are less than or equal to \( n \):**
   Let \( a \) be the largest integer such that \( a^3 \leq n \). This means \( (a+1)^3 > n \).

2. **Determine the divisors:**
   The integers whose cubes are less than or equal to \( n \) are \( 1, 2, 3, \ldots, a \). Therefore, \( n \) must be divisible by all these integers.

3. **Find the least common multiple (LCM):**
   To ensure \( n \) is divisible by all integers from \( 1 \) to \( a \), \( n \) must be at least the LCM of these integers. The LCM of the first \( k \) integers is denoted as \( \text{LCM}(1, 2, \ldots, k) \).

4. **Estimate \( a \):**
   We need to find the largest \( a \) such that \( \text{LCM}(1, 2, \ldots, a) \leq a^3 \).

5. **Calculate the LCM for increasing values of \( a \):**
   - For \( a = 1 \): \( \text{LCM}(1) = 1 \)
   - For \( a = 2 \): \( \text{LCM}(1, 2) = 2 \)
   - For \( a = 3 \): \( \text{LCM}(1, 2, 3) = 6 \)
   - For \( a = 4 \): \( \text{LCM}(1, 2, 3, 4) = 12 \)
   - For \( a = 5 \): \( \text{LCM}(1, 2, 3, 4, 5) = 60 \)
   - For \( a = 6 \): \( \text{LCM}(1, 2, 3, 4, 5, 6) = 60 \)
   - For \( a = 7 \): \( \text{LCM}(1, 2, 3, 4, 5, 6, 7) = 420 \)
   - For \( a = 8 \): \( \text{LCM}(1, 2, 3, 4, 5, 6, 7, 8) = 840 \)
   - For \( a = 9 \): \( \text{LCM}(1, 2, 3, 4, 5, 6, 7, 8, 9) = 2520 \)

6. **Compare LCM with \( a^3 \):**
   - For \( a = 7 \): \( 7^3 = 343 \) and \( \text{LCM}(1, 2, 3, 4, 5, 6, 7) = 420 \). Since \( 420 > 343 \), \( a = 7 \) is not valid.
   - For \( a = 8 \): \( 8^3 = 512 \) and \( \text{LCM}(1, 2, 3, 4, 5, 6, 7, 8) = 840 \). Since \( 840 > 512 \), \( a = 8 \) is not valid.
   - For \( a = 9 \): \( 9^3 = 729 \) and \( \text{LCM}(1, 2, 3, 4, 5, 6, 7, 8, 9) = 2520 \). Since \( 2520 > 729 \), \( a = 9 \) is not valid.

7. **Verify the largest valid \( a \):**
   The largest \( a \) for which \( \text{LCM}(1, 2, \ldots, a) \leq a^3 \) is \( a = 6 \), since \( \text{LCM}(1, 2, 3, 4, 5, 6) = 60 \) and \( 6^3 = 216 \).

Conclusion:
The greatest positive integer \( n \) for which \( n \) is divisible by all positive integers whose cube is not greater than \( n \) is \( \boxed{60} \).
