If it helps to remember which to use, "devoir" implies a duty towards someone. As a noun, it can mean a debt (financial or otherwise), or even school homework. "Falloir" expresses a need for, or shortage of something.

Hence: "Il faut faire nos devoirs." = "We need to do our assignments."

Is falloir conjugated with il/elle/on, while devoir conjugated with all pronouns?

falloir can only be conjugated with the impersonal "il". Never with any of the others.

http://conjugator.reverso.net/conjugation-french-verb-falloir.html I think here written il/elle faut. Give it a look

If you look on wordreference it only shows il being used. : http://www.wordreference.com/conj/FrVerbs.aspx?v=falloir

I'm no expert, but I have never seen anything other than Il faut.

Devoir can be used with all personal pronouns: je, tu, il/elle/on, nous, vous, ils/elles: Je dois partir – I have to leave Nous devons attendre – We have to wait   Devoir  when followed by an infinitive, expresses an obligation, probability, or supposition.

Falloir can only be used with one pronoun: il (impersonal ‘it’):

Il faut partir – It must go Il faut que je te parle – I have to talk to you (literally: It has to that I speak to you)   Falloir is stronger and somewhat more formal than devoir ; it expresses necessity. Falloir can be used with an infinitive or the subjunctive. Because it’s an impersonal verb, falloir does not conjugate for different subjects. In order to specify the person who needs to do something, you can either use the subjunctive or an indirect object pronoun with the infinitive.   Devoir can be used with all personal pronouns: je, tu, il/elle/on, nous, vous, ils/elles:

Je dois partir – I have to leave Nous devons attendre – We have to wait Falloir can only be used with one pronoun: il (impersonal ‘it’): Il faut partir – Must go Il faut que je te parle – I have to talk to you (literally: It must/requires that I speak to you)

"Falloir" is impersonal and means "to be necessary." "Devoir" can be used with all subjects and means "must" or "have to."
