How many Horcruxes did Lord Voldemort make in the 'Harry Potter' series?

Voldemort made seven Horcruxes. Harry destroyed one in his second year and Dumbledore destroyed one just before his sixth year which left five Horcruxes to destroy (although he only thought there was four). In the end, every Horcrux was destroyed by different people (Harry, Dumbledore, Ron, Hermione, Crabbe, Voldemort, Neville)
