It is the order of Allah ( SWT) for every Muslim to pray Fajr Namaz in two Rak'ats, Dhuhr ( Zohr) Namaz in four Rak'ats, Asr Namaz in four Rak'ats, Maghrib Namaz in three Rak'ats and Isha Namaz in Four Rak'ats. Allah knows the full reason behind every order. It is like our Tawaf around Ka'bah to be seven rounds, no less and no more than seven rounds in every Tawaf. 
The Quran orders us to obey and follow the Prophet (Sura 59, Verse 7) and the Prophet (SAWA) ordered us to pray as we saw him praying. ( Wasa'il al-Shia and Bukhari).

We must obey Allah by obeying the Prophet and we must pray same number of Rak'ats prayed by the Prophet in different prayers.
