$-1 xx 2^3 xx 3 xx 5 xx s xx t^3$

A minus requires a -1 factor

$120 = 2 xx 60$
$2 xx 60 = 2 xx 2 xx 30$
$2 xx 2 xx 30 = 2 xx 2 xx 2 xx 15$
$2 xx 2 xx 2 xx 15 = 2 xx 2 xx 2 xx 3 xx 5$

$st^3 = s xx t xx t xx t$ or $st^3$

so

$-1 xx 2 xx 2 xx2 xx 3 xx 5 xx s xx t xx t xx t$ =

$-1 xx 2^3 xx 3 xx 5 xx s xx t^3$
