divisors

abjad.mathtools.divisors.divisors(n)

Gets positive divisors of n in increasing order.

>>> abjad.mathtools.divisors(84)
[1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84]

>>> for x in range(10, 20):
...     print(x, abjad.mathtools.divisors(x))
...
10 [1, 2, 5, 10]
11 [1, 11]
12 [1, 2, 3, 4, 6, 12]
13 [1, 13]
14 [1, 2, 7, 14]
15 [1, 3, 5, 15]
16 [1, 2, 4, 8, 16]
17 [1, 17]
18 [1, 2, 3, 6, 9, 18]
19 [1, 19]

Allows nonpositive n:

>>> abjad.mathtools.divisors(-27)
[1, 3, 9, 27]

Raises not implemented error on 0.

Returns list of positive integers.
