When drawing four cards, where you do NOT replace a card before drawing another card, what is the probability of drawing "four of a kind"?

Can you show me the steps.

well, there are 52 cards in the deck, 13 of each suit
4 of each kind, like four kings
so what is the probability of drawing four kings?
4/52 *3/51*2/50 *1/49

multiply that by 13 because it could have been four threes or four sevens or whatever
