- Factors[ <Polynomial> ]
- 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.

- 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:
Factors[1024]
returns {(2,10)}, because 1024=210.Factors[42]
returns {(2,1),(3,1),(7,1)}, because 42=213171.
