FactorTerms[poly]
pulls out any overall numerical factor in poly.

pulls out any overall factor in poly that does not depend on x.

pulls out any overall factor in poly that does not depend on any of the

FactorTerms automatically threads over lists in poly, as well as equations, inequalities and logic functions.

Pull out an overall numerical factor, but do no further factoring:

Out[1]=

Define a larger polynomial:

Pull out an overall numerical factor:

Pull out factors that do not depend on x:

Pull out factors that do not depend on x and y and then factors that do not depend on x:

Pull out overall numerical factor over integers modulo 7:

Expand distributes the common factor over the terms, effectively reverting FactorTerms:

FactorTermsList gives a list of factors:

Factor performs a complete factorization:
