There are 16 AK's out of 52*51/2 = 1,326 hands. Once one player gets AK, there are 9 left out of 50*49/2 = 1,225 hands. Once two players get AK, there are 4 left out of 48*47/2 = 1,128. The last player has only one AK to get out of 46*45/2 = 1,035 hands.

Multiply them all together and you get 576 chances in 3,792,792,276,000 or 2 in 13,169,417,625. With 9 players there are 9*8*7*6/(4*3*2*1) = 126 different ways to choose the four players. That makes it about 1 time in 52 million.
