555

Not sure what you want with “555.” Do you mean the number itself, or something about Thai usage (555 = haha), or is this a prompt for a problem you’re stuck on?

If you want a quick math thing for exam prep, here’s a ready mini-problem and solution:

• Find the prime factorization of 555.
  • 5+5+5 = 15, divisible by 3, so 555 ÷ 3 = 185.
  • 185 = 5 × 37.
  • So 555 = 3 × 5 × 37.
