With the help of sympy.factorint() method, we can find the factors and their corresponding multiplicities of a given integer. For input less than 2, factorint() behaves as follows:
– returns the empty factorization {}.- – returns
. 
– adds 
to the factors and then factors 
.
– returns the empty factorization {}.
– returns 
.
– adds 
to the factors and then factors 
.
Syntax:
factorint(n)Parameter:
n – It denotes an integer.Returns:
Returns a dictionary containing the prime factors of n as keys
and their respective multiplicities as values.
Example #1:
# import factorint() method from sympy from sympy import factorint n = 2**3 * 3**4 * 5**6 # Use factorint() method factor_dict = factorint(n) print("Dictionary containing factors of {} with respective multiplicities : {}". format(n, factor_dict)) |
Output:
Dictionary containing factors of 10125000
with respective multiplicities : {2: 3, 3: 4, 5: 6}
Example #2:
# import factorint() method from sympy from sympy import factorint n = 6**4 * 13 # Use factorint() method factor_dict = factorint(n) print("Dictionary containing factors of {} with respective multiplicities : {}". format(n, factor_dict)) |
Output:
Dictionary containing factors of 16848
with respective multiplicities : {2: 4, 3: 4, 13: 1}
