When I was looking for the song about the shillelagh for my previous post, I found another one called Two-Shillelagh O’Sullivan also by Bing Crosby. It wasn’t a song from my childhood, but it inspired me to make a puzzle with two shillelaghs anyway. In the song, O’Sullivan wears these walking sticks in a holster and can draw them quicker than anyone can draw a gun. He was impossible to beat.
This two-shillelagh puzzle is also a bit difficult to beat. You’re not going to let that stop you from trying, are you? Just use logic and your knowledge of the multiplication table.
Write the numbers from 1 to 12 in the first column and again in the top row so that those numbers are the factors of the given clues.
Here’s the same puzzle in black and white:
Factors of 1758:
- 1758 is a composite number.
- Prime factorization: 1758 = 2 × 3 × 293.
- 1758 has no exponents greater than 1 in its prime factorization, so √1758 cannot be simplified.
- The exponents in the prime factorization are 1, 1, and 1. Adding one to each exponent and multiplying we get (1 + 1)(1 + 1)(1 + 1) = 2 × 2 × 2 = 8. Therefore 1758 has exactly 8 factors.
- The factors of 1758 are outlined with their factor pair partners in the graphic below.
