With the help of sympy.primenu() method, we can calculate the number of distinct prime factors for a given positive integer.
Syntax: primenu(n)
Parameter:
n – It denotes an integer.Returns: Returns the number of distinct prime factors for the given positive integer.
Example #1:
# import primenu() method from sympy from sympy.ntheory.factor_ import primenu
n = 24
# Use primenu() method primenu_n = primenu(n)
print("Number of distinct prime factors of {} = {} ".format(n, primenu_n)) # 2 and 3
|
Output:
Number of distinct prime factors of 24 = 2
Example #2:
# import primenu() method from sympy from sympy.ntheory.factor_ import primenu
n = 2 * 3*7 * 11 * 13
# Use primenu() method primenu_n = primenu(n)
print("Number of distinct prime factors of {} = {} ".format(n, primenu_n))
|
Output:
Number of distinct prime factors of 6006 = 5
