My teacher has been giving even more confusing homework every since she found out about my online help. Today's assignment was supposed to be easy enough: only some factorization, kids' stuff. But when I received my sample problems, I realized that I would be needing some help again. So would you mind giving me assistance for another time?

$75678 = 47*96*13$  
$53271 = 53*33*83$  
$707821 = 11*31*76*7$  
$236783 = 73*46*12*22*2$  
$5769471 = \ ?$
