# 248 Convert to Roman Numeral

<-- Enter Positive Number less than 4000 or a Roman Numeral with numeric value less than 4000

Convert 248 to a Roman numeral given that I=1, V=5, X=10, L=50, C=100, D=500, and M=1,000

We start with a total letter value of 248 that we want to work backwards with each letter until 0.
We want to build a Roman numeral term letter by letter as well, starting with nothing.
Dividing our current quantity of 248 by each Roman numeral Value, we need 2 of letter C
We piece that together with our Roman numeral(s) term of to get: + CC = CC
Since we needed 2 of the letter C, our total value of letters becomes: 2 * 100 = 200
Our new decreasing total now becomes: 248 - 200 = 48

Dividing our current quantity of 48 by each Roman numeral Value, we need 4 of X
Since we want 3 or less of a letter, we need to do subtraction by writing the next letter of L in front of X
We piece that together with our Roman numeral(s) term of CC to get: CC + XL = CCXL
Since we needed 1 of the letter X and 1 of the letter L, our total value of letters becomes: 50 - 10 = 40
Our new decreasing total now becomes: 48 - 40 = 8

Dividing our current quantity of 8 by each Roman numeral Value, we need 1 of letter V
We piece that together with our Roman numeral(s) term of CCXL to get: CCXL + V = CCXLV
Since we needed 1 of the letter V, our total value of letters becomes: 1 * 5 = 5
Our new decreasing total now becomes: 8 - 5 = 3

Dividing our current quantity of 3 by each Roman numeral Value, we need 3 of letter I
We piece that together with our Roman numeral(s) term of CCXLV to get: CCXLV + III = CCXLVIII
Since we needed 3 of the letter I, our total value of letters becomes: 3 * 1 = 3
Our new decreasing total now becomes: 3 - 3 = 0

Since our decreasing total now equals 0, we have our answer of CCXLVIII
