There are an infinite number of them. The smallest one
is 63, and the rest are all the multiples of 63.
Yes, 9 can go into 21, but not evenly. When you divide 21 by 9, the result is 2 with a remainder of 3, meaning 9 fits into 21 two times. Thus, 9 does divide into 21, but it does not result in a whole number.

9/21 = 0.4286 so 43% of 21 = 9.03 = 9 rounded to whole number.
The number 63 can be evenly divided by 1, 3, 7, 9, 21, and 63.
The smallest number that both 21 and 23 can go into is 483.

The mixed number of 21 over 9 is 21/3
1, 3, 7, 9, 21, 63
9/21 = 0.4286 so 43% of 21 = 9.03 = 9 rounded to whole number.
9 and 6 9 + 6 = 15 126/9 = 14 126/6 = 21
The number 63 can be evenly divided by 1, 3, 7, 9, 21, and 63.
The smallest number that both 21 and 23 can go into is 483.
