Step 1: Let the smaller number be \(x\).
Then, the larger number will be \(3x\).
Step 2: Apply the condition given.
\[
3x - x = 26 \implies 2x = 26 \implies x = 13
\]
Step 3: Find both numbers.
Smaller number \(= 13\), Larger number \(= 3x = 39\).
Step 4: Conclusion.
Hence, the two numbers are \(\boxed{13 \text{ and } 39}\).
