Did two or three angels visit Prophet Lut and Ibrahim?

I noticed that "2 angels" and "3 angels" were mentioned in different sites. Specifically, Islami City writes: > Upon Lut’s prayer, Allah sent two angels in the form of men. These angels visited Ibrahim before coming to Lut. whereas Hadith of the Day writes: > The three angels – said to have been Jibrael AS, Mikael AS and Israfil AS – then arrived at the outskirts of Lut’s AS town in the form of very handsome human beings. Which is it? I tried to read Qu'ran and it said "the angels".
