Now I’ll write a little bit about the puzzle number, 1411:

- 1411 is a composite number.
- Prime factorization: 1411 = 17 × 83
- 1411 has no exponents greater than 1 in its prime factorization, so √1411 cannot be simplified.
- The exponents in the prime factorization are 1, and 1. Adding one to each exponent and multiplying we get (1 + 1)(1 + 1) = 2 × 2 = 4. Therefore 1411 has exactly 4 factors.
- The factors of 1411 are outlined with their factor pair partners in the graphic below.

1411 is the hypotenuse of a Pythagorean triple:

664-1245-1411 which is (8-15-**17**) times **83**.
