the game of Razz is played by 2 people using number cards,each card containing a number between 10 and 50.These cards are placed face down.In turn,each player turns up 4cards,chooses one and turns the other 3 back down.The winner is the first player who obtains 3 cards with the same factor(1 excluded).If these 4 cards turned up on your first turn,which one would you keep?why?24,30,35,36

I imagine you'd want to keep the card with the largest number of factors. 24 has got the following factors: {2, 3, 4, 6, 8, 12}, so there are 6 of them. 30 has got {2, 3, 5, 6, 10, 15}, so there are 6 of them. 35 has got {5, 7} so there are just 2. 36 has got {2, 3, 4, 6, 9, 12, 18}, so there are 7. It looks like 36 is the best bet.
