The primefactors method is used to return a sorted list of prime factors of a given number.
Note: Prime factors are prime numbers that completely divide the given number to get zero as the remainder.
Syntax
sympy.primefactors(n)
Parameters
n: This is the number for which prime factors need to be obtained.
Return value
The method returns the prime factors of the given number.
Code example
import sympyn = 100print("The prime factors of %s is %s" % (n, sympy.primefactors(n)))
Code explanation
- Line 1: We import the
sympypackage. - Line 3: We define
n. - Line 5: We use the
sympy.primefactors()method to obtain the prime factors ofn.
