Where 1907 fits
Why 1907 is special
Bakelite was the first fully synthetic plastic, made from molecules that do not occur in nature. Every subsequent plastic descends from the demonstration that such materials could be designed rather than found.

In historical numeral systems
Egyptian
1 lotus, 9 coils of rope, 7 strokes
1 × 1,000 + 9 × 100 + 7 × 1 = 1,907. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 1 vertical wedge (sixties place), 4 corner wedges + 7 vertical wedges (units place)
31 × 60 + 47 = 1907. 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.

Common questions
Is 1907 a prime number?
Yes, 1907 is prime — it has exactly two positive divisors: 1 and itself.
What are the factors of 1907?
The factors of 1907 are 1, 1907.
What is 1907 in Roman numerals?
