3 is one such number.
Seven goes into both 63 and 77
315
63
40 and 63 have no common prime factors.
The highest number that both 63 and 14 go into is infinity. They go into infinity an infinite number of times (as does every other number). I'm not sure if you have asked the right question, but if you have then the answer is infinity. If, however, you meant, "what is the highest common factor of both 63 & 14?", then the answer is 7. 63 = 9 * 7 and 14 = 2 * 7.
Any multiple of 63.
