"...that any morphism from G into an Abelian group factors through G / G' "

Is this just another way of asking to show that \frac{G}{\ker \phi} is normal in \frac{G}{G'}? The wording of this question is a little unclear to me.


Answer. More fully, you have to show that given any group homomorphism \phi:G\to A, where A is an Abelian group, there exists a group homomorphism \bar\phi:G/G'\to A such that \phi=\bar\phi\circ\pi, where \pi is the projection \pi:G\to G/G'.
