◆ primeFactorisation()

lists primeFactorisation ( const number  n,
const int  pBound 
)

Factorises a given bigint number n into its prime factors less than or equal to a given bound, with corresponding multiplicities.

The method finds all prime factors with multiplicities. If a positive bound is given, then only the prime factors <= pBound are being found. In this case, there may remain an unfactored portion m of n. Also, when n is negative, m will contain the sign. If n is zero, m will be zero. The method returns a list L filled with three entries: L[1] a list; L[1][i] contains the i-th prime factor of |n| as int or bigint (sorted in ascending order), L[2] a list; L[2][i] contains the multiplicity of L[1, i] in |n| as int L[3] contains the remainder m as int or bigint, depending on the size,

We thus have: n = L[1][1]^L[2][1] * ... * L[1][k]^L[2][k] * L[3], where k is the number of mutually distinct prime factors (<= a provided non- zero bound). Note that for n = 0, L[1] and L[2] will be emtpy lists and L[3] will be zero.

Returns
the factorisation data in a SINGULAR-internal list
Parameters
