What was the most significant factor in Hitler's consolidation of power?

One factor that contributed to Hitler's rise to and consolidation of power was his propaganda scheme, which was implemented extensively into Germany. Creditable mainly to one of his most trusted officers, Joseph Goebbels, the Nazi party released consistent messages over a range of media platforms to reinforce and advertise Nazi ideologies. From the earliest stages of the Nazi party, they had already established a magazine which would advertise Nazi aims. These developed simultaneously as the party evolved. Not only did the publish magazines, but also moved onto establishing a radio program and most notably and frequently posters and propaganda images. These covered a complete range of Nazi ideologies, from Aryan supremacy, to the 'ideal' hegemonic nuclear family structure, to anti-Semitic views. These were increasingly circulated with the rise of the party, and the resultant effect was an increase in the German population's interest, attention and curiosity in the party, thus also strengthening the support base. Subsequently, with the rise of the party's popularity, Hitler became closer to consolidating his position as supreme leader of the state.It cannot be doubted that Nazi propaganda catalyzed Hitler's rise and consolidation of power, however one could argue there was one more significant: The Enabling Act of March 1933. Following the public fear instigated by the Reichstag Fire a month prior to the Enabling Act, Hitler with his position as Chancellor succeeded in convincing President Hindenburg to pass the Act, which fundamentally allowed him to pass legislation without the permission of the president or the Reichstag, should it fulfill the criteria of an 'emergency.' Hitler immediately exploited this ability, and used it to eliminate his opponents with quick succession. He made it illegal for the assembly parties, specifically the communist party. He also used his SA (personal paramilitary 'Stormtroopers' group) to intimidate non-Nazi officers and party members. Through doing so, Hitler efficiently eliminated opposition, clearing the way for him to lead the Nazi party right to the top, and consolidating his position as their leader and the leader of the rest of an intimidated and vulnerable German state.
