555

Not sure what you want with "555." Here are a few quick angles in case you’re studying math:

• Prime factorization: 555 = 3 × 5 × 37
• Divisibility: sum of digits = 15, so divisible by 3; ends with 5, so divisible by 5; hence divisible by 15. 555/15 = 37
• Example quick problems:
  • gcd(555, 420) = 15
  • 555 × 2 = 1110
  • 555 in words: five hundred fifty-five
• If you meant 5×5×5 = 125 or 5^5 = 3125, or 5+5+5 = 15, tell me which one.

If you share the subject and level, I can tailor a short practice problem or explanation.
