Where 913 fits
Why 913 is special
It is the parent of prototype pollution and similar weaknesses, where a language's own extensibility is the attack surface.

CMXIII uses the subtractive pair CM: a hundred before a thousand — a thousand minus a hundred.
Binary
1 1 1 0 0 1 0 0 0 1
1 × 512 + 1 × 256 + 1 × 128 + 0 × 64 + 0 × 32 + 1 × 16 + 0 × 8 + 0 × 4 + 0 × 2 + 1 × 1 = 913
Octal

1 × 512 + 6 × 64 + 2 × 8 + 1 × 1 = 913
Hexadecimal
3 9 1
3 × 256 + 9 × 16 + 1 × 1 = 913
Read as powers of two: 512 + 256 + 128 + 16 + 1 = 913.
In historical numeral systems
Egyptian
9 coils of rope, 1 hobble, 3 strokes
9 × 100 + 1 × 10 + 3 × 1 = 913. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 5 vertical wedges (sixties place), 1 corner wedge + 3 vertical wedges (units place)
15 × 60 + 13 = 913. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then iota, then gamma, marked as a numeral
sampi-iota-gamma + keraia
sampi + iota + gamma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then tav, then qof, then yod, then gimel
tav-tav-qof-yod-gimel
tav (400) + tav (400) + qof (100) + yod (10) + gimel (3) = 913, written in descending order.
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.

Common questions
Is 913 a prime number?
No, 913 is not prime.
What are the factors of 913?
The factors of 913 are 1, 11, 83, 913.
What is 913 in Roman numerals?
913 in Roman numerals is CMXIII. CM is subtractive: a hundred before a thousand — a thousand minus a hundred. Written additively it would be DCCCCXIII, which Roman inscriptions used freely — the strict subtractive form is a later convention.
