555

Do you want something specific about 555 (math properties, factoring, representations) or did you mean something else? Here are quick math notes:

• Factorization: 555 = 3 × 5 × 37 (all distinct primes)
• Divisibility: divisible by 3 and by 5; not by 9
• Basic representations:
  • Decimal: 555
  • Binary: 1000101011₂
  • Hexadecimal: 0x22B
  • Roman numerals: DLV
• Divisors: 1, 3, 5, 15, 37, 111, 185, 555 (8 divisors)
• Sum of divisors: σ(555) = 912
• Representations as a sum of consecutive integers: 8 ways (including 555 itself)

If you want, tell me the exam topic (divisibility, factorization, number of representations, etc.) and I’ll tailor a solution or example.
