Level 2 puzzles aren’t very tricky, but maybe this one is a little bit. Can you write the factors from 1 to 12 in both the first column and the top row so that this puzzle functions as a multiplication table?
Print the puzzles or type the solution in this excel file: 12 factors 942-950
Now I’ll write something about the number 943:
943 is the hypotenuse of a Pythagorean triple:
207-920-943 which is 23 times (9-40-41)
It is also a leg in two primitive Pythagorean triples:
576-943-1105, calculated from 2(32)(9), 32² – 9², 32² + 9²
943-444624-444625, calculated from 472² – 471², 2(472)(471), 472² + 471²
- 943 is a composite number.
- Prime factorization: 943 = 23 × 41
- The exponents in the prime factorization are 1 and 1. Adding one to each and multiplying we get (1 + 1)(1 + 1) = 2 × 2 = 4. Therefore 943 has exactly 4 factors.
- Factors of 943: 1, 23, 41, 943
- Factor pairs: 943 = 1 × 943 or 23 × 41
- 943 has no square factors that allow its square root to be simplified. √943 ≈ 30.708305
