Now I’ll write a little bit about the number 1167:

- 1167 is a composite number.
- Prime factorization: 1167 = 3 × 389
- 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 1167 has exactly 4 factors.
- Factors of 1167: 1, 3, 389, 1167
- Factor pairs: 1167 = 1 × 1167 or 3 × 389
- 1167 has no square factors that allow its square root to be simplified. √1167 ≈ 34.16138

1167 is the hypotenuse of a Pythagorean triple:

567-1020-1167 which is **3** times (189-340-**389**)

1167 is palindrome 5D5 in BASE 14 (D is 13 base 10)

because 5(14²) + 13(14) + 5(1) = 1167
