How many times can the roman numeral be repeated?

Answer 1

None if its: V, L or D because V+V=X, L+L=C and D+D=M

Only four times if its: I, X, C or M because I+I+I+I+I=V, X+X+X+X+X=L, C+C+C+C+C=D and M+M+M+M+M=(V)

Answer 2

In traditional Roman numerals, each symbol can be repeated up to three times in a row. For example, III represents the number 3. However, there are alternative forms of Roman numerals that allow for larger repetitions, but these are not commonly used.
