- Returns list of lists {factor,exponent} such that product of all these factors raised to corresponding exponents equals the given polynomial.
Note: Not all of the factors are irreducible over the reals.

Description of command / feature needed. Please enter it instead of this template into Manual:Factors Command. so that it's included also to the public namespace. For more details see Project:HowTo |
- Factors[ <Number> ]
- Returns list of lists {prime,exponent} such that product of all these primes raised to corresponding exponents equals the given number. Primes are sorted in ascending order.
Example:
PrimeFactorization[1024]returns {(2,10)}, because 1024=210.PrimeFactorization[42]returns {(2,1),(3,1),(7,1)}, because 42=213171.
Note: See also PrimeFactors Command.
