Where 3422 fits
Why 3422 is special
That is why it was used for light bulb filaments: a filament must glow white-hot without melting. The same property makes it useful in rocket nozzles and armour-piercing projectiles.

In historical numeral systems
Egyptian
3 lotuses, 4 coils of rope, 2 hobbles, 2 strokes
3 × 1,000 + 4 × 100 + 2 × 10 + 2 × 1 = 3,422. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 corner wedges + 7 vertical wedges (sixties place), 2 vertical wedges (units place)
57 × 60 + 2 = 3422. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Lead melts at about 327 degrees, low enough for a wood fire, and tungsten at 3,422, the highest of any metal. The span between them is most of what determines which metals ancient societies could use.

Science
Tungsten withstands about 3,422 degrees before melting, which is why incandescent filaments were made of it. Anything that must stay solid while glowing white-hot converges on the same element.

Is 3422 a prime number?
No, 3422 is not prime.
What are the factors of 3422?
The factors of 3422 are 1, 2, 29, 58, 59, 118, 1711, 3422.
What is 3422 in Roman numerals?
