Where 3480 fits
Why 3480 is special
It is why airlines refuse loose power banks in the hold, and the reason spare batteries must travel in the cabin where a fire can be seen and reached.

MMMCDLXXX uses the subtractive pair CD: a hundred before five hundred — five hundred minus a hundred.

Read as powers of two: 2,048 + 1,024 + 256 + 128 + 16 + 8 = 3,480.
In historical numeral systems
Egyptian
3 lotuses, 4 coils of rope, 8 hobbles
3 × 1,000 + 4 × 100 + 8 × 10 = 3,480. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 corner wedges + 8 vertical wedges (sixties place), empty units place
58 × 60 + 0 = 3480. Places are separated by a space on the tablet, with the higher place written first. The second place is empty, and this is precisely the case the early system could not write unambiguously — the same wedges alone would also read as 1.
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.

Technology & computing
UN 3480 identifies lithium-ion batteries shipped without equipment, classified as a Class 9 dangerous good. Air transport rules restrict state of charge and require cabin carriage of spares.

Common questions
Is 3480 a prime number?
No, 3480 is not prime.
What are the factors of 3480?
The factors of 3480 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 29, 30, 40, 58, 60, 87, 116, 120, 145, 174, 232, 290, 348, 435, 580, 696, 870, 1160, 1740, 3480.
What is 3480 in Roman numerals?
3480 in Roman numerals is MMMCDLXXX. CD is subtractive: a hundred before five hundred — five hundred minus a hundred. Written additively it would be MMMCCCCLXXX, which Roman inscriptions used freely — the strict subtractive form is a later convention.
