Python | sympy.udivisors() method

With the help of sympy.udivisors() method, we can find all the unitary divisors of a given number in sorted order by default.

Syntax: udivisors(n, generator=False)

Parameter:
n – It denotes an integer.
generator – If generator is True an unordered generator object is returned, otherwise it returns a sorted list of unitary divisors. It is False by default.

Returns: Returns a list of all the unitary divisors of the given integer.

Example #1:

# import udivisors() method from sympy
from sympy.ntheory.factor_ import udivisors

n = 84

# Use udivisors() method
udivisors_n = udivisors(n)

print("The unitary divisors of {} : {}".format(n, udivisors_n))

Output:

The unitary divisors of 84 : [1, 3, 4, 7, 12, 21, 28, 84]

Example #2:

# import udivisors() method from sympy
from sympy.ntheory.factor_ import udivisors

n = -210

# Use udivisors() method
udivisors_n = list(udivisors(n, generator = True))

print("The unitary divisors of {} : {}".format(n, udivisors_n))

Output:

The unitary divisors of -210 : [1, 2, 3, 6, 5, 10, 15, 30, 7, 14, 21, 42, 35, 70, 105, 210]
