If you have hole cards that can flop a royal, then there is only 1 royal flop out of 50*49*48/6 = 19,600 total flops, so the odds are 19,599:1.

For example, if you hold JhTh, then the only royal flop would be the one containing Qh Kh Ah. You can also compute the probability of this flop as 3/50 * 2/49 * 1/48 = 1/19,600 or odds of 19,599:1.
