Now I’ll share some information about the puzzle number, 1355:

- 1355 is a composite number.
- Prime factorization: 1355 = 5 × 271
- 1355 has no exponents greater than 1 in its prime factorization, so √1355 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 1355 has exactly 4 factors.
- The factors of 1355 are outlined with their factor pair partners in the graphic below.

1355 is the hypotenuse of a Pythagorean triple:

813-1084-1355 which is (3-4-**5**) times **271**
