Theorem
The smallest sequence of quadruplets of consecutive integers each of which is divisible by a cube greater than $1$ is:
- $\tuple {22 \, 624, 22 \, 625, 22 \, 626, 22 \, 627}$
Proof
\(\ds 22 \, 624\) | \(=\) | \(\ds 2828 \times 2^3\) | ||||||||||||
\(\ds 22 \, 625\) | \(=\) | \(\ds 181 \times 5^3\) | ||||||||||||
\(\ds 22 \, 626\) | \(=\) | \(\ds 838 \times 3^3\) | ||||||||||||
\(\ds 22 \, 627\) | \(=\) | \(\ds 17 \times 11^3\) |
This theorem requires a proof. In particular: It remains to be shown there is no smaller such quadruplet. You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof.
