any integer

Description

• 

The isqrfree function returns the square-free integer factorization of the integer n.

• 

The function returns the result in the form [u,[[p1,ⅇ1],...,[pm,ⅇm]] where pi is a positive factor of n, ei is its multiplicity, gcdpi,pj=1 for all ij, and u is the sign of n. The square-free factorization of n is: n=up1ⅇ1...pmⅇm.
