What is the number doors to Hell and Paradise?

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Paradise has eight gates based upon the Hadith reported from Ubadah that the Prophet (Sallallahu Alaihi wa Sallam) said: "If anyone testifies that none has the right to be worshipped but Allah Alone Who has no partners, and that Muhammad is His Slave and His Apostle, and that Jesus is Allah's Slave and His Apostle and His Word which He bestowed on Mary and a Spirit created by Him, and that Paradise is true, and Hell is true, Allah will admit him into Paradise with the deeds which he had done even if those deeds were few" . ( Junada , the sub-narrator said, 'Ubada added, "Such a person can enter Paradise through any of its eight gates he likes" .
Imam Muslim narrated from Umar (Radiya Allahu Anhu) that the Prophet (Sallallahu Alaihi wa Sallam) said: "If anyone amongst you performs the ablution, and then completes the ablution well and then says: I testify that none has the right to be worshipped but Allah and that Muhammad is the servant of Allah and His Messenger, the eight gates of Paradise would be opened for him and he may enter by whichever of them he wishes" .
The Hell has seven gates as Allah Says (interpretation of meaning): {"And surely, Hell is the promised place for them all. "It (Hell) has seven gates, for each of those gates is a (special) class (of sinners) assigned.} [15: 43-44].
Allah knows best.
