555

Could you tell me what you want to do with 555? Here are a few quick angles:

• Math basics:

  • Prime factorization: 555 = 3 × 5 × 37
  • Divisors: 1, 3, 5, 15, 37, 111, 185, 555
  • It’s a palindrome (555), and in Roman numerals it’s DLV
  • Binary: 555 = 1000101011

• If you’re studying electronics: the 555 timer IC and its common configurations (astable, monostable, bistable)

• Quick practice prompt (if you want): Prove 555 is not prime and list all divisors; or convert 555 to binary and back.
