555

Do you mean the number 555 (math), or something else (like slang for laughter in Thai/Chinese, or a Roman numeral)? If you’re studying, here are quick math facts you can reuse:

• Prime factorization: 555 = 3 × 5 × 37
• Divisors: 1, 3, 5, 15, 37, 111, 185, 555
• It’s an odd composite number (not prime)
• Roman numeral: 555 = DLV
• Digit sum: 5 + 5 + 5 = 15 (divisible by 3)
