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.
Example: Factors[x^8-1] returns {{x-1,1},{x+1,1},{x^2+1,1},{x^4+1,1}}.
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.
