Notwithstanding todays configuration of Roman numerals inasmuch that there is evidence to suggest that the ancient Romans would have written the equivalent of one to a million as follows:-
Units: I, II, III, IIII, V, VI, VII, VIII and VIIII
Tens: X, XX, XXX, XXXX, L, LX, LXX, LXXX and LXXXX
Hundreds: C, CC, CCC, CCCC, D, DC, DCC, DCCC and DCCCC
Thousands: (I), (II), (III), (IIII), (V), (VI), (VII), (VIII) and (VIIII)
Tens of thousands: (X), (XX), (XXX), (XXXX), (L), (LX), (LXX), (LXXX) and (LXXXX)
Hundreds of thousands: (C), (CC), (CCC), (CCCC), (D), (DC), (DCC), (DCCC) and (DCCCC)
Million: (M)
To select any numerals simply write them out in descending order and then abridge them whenever possible as in the following examples:-
900,000 = (DCCCC) = (CM)
90,000 = (LXXXX) = (XC)
9,000 = (VIIII) = (IX)
900 = DCCCC = C(I) or as CM
90 = LXXXX = XC
9 = VIIII = IX
999,999 = (DCCCCLXXXXVIIII)DCCCCLXXXXVIIII = I(M)
Check:-
(CM)+(XC) = (XM) = 990,000
(XM)+(IX) = (IM) = 999,000
(IM)+CM = C(M) = 999,900
C(M)+XC = X(M) = 999,990
X(M)+IX = I(M) = 999,999
Note that numerals within brackets indicate multiplication by a thousand and that the practice of placing a bar above a numeral to indicate multiplication by a thousand was introduced during the Middle Ages along with other rules and regulations governing todays Roman numeral system.
QED
What are all the prime numbers in Roman numerals?
You'll find the possible answer in the question: What are the numbers from 1 to a 1000000 in Roman numerals?
one thousand M's
On Converting between Arabic and Roman Numbers ,we get :1 8970 in roman numerals is : MMMMMMMMCMLXX
The equivalent prime numbers from 1 to 10 in Roman numerals are: II, III, V and VII
1 Million would be (M). That means M, which is a thousand, needs to be multiplied by another thousand. 1000*1000=1,000,000 or (M)
