Here’s some stuff that you probably didn’t know about the number 995:
995 has only two factor pairs, and they both use the exact same digits (1, 9, 9, 5):
1 × 995 = 199 × 5

597-796-995 which is (3-4-5) times 199
It is palindrome 3E3 in BASE 16 (E is 14 base 10) because 3(16²) + 14(16) + 3(1) = 995
- 995 is a composite number.
- Prime factorization: 995 = 5 × 199
- 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 995 has exactly 4 factors.
- Factors of 995: 1, 5, 199, 995
- Factor pairs: 995 = 1 × 995 or 5 × 199
