Best Answer

The Roman Numeral for 23 is: XXIII

Tally Marks: llll llll llll llll lll

It is a deficiant number, meaning all the proper factors add up to less than the number itself. (So 1 equals less than 23)

The first 5 multiples are: 23, 46, 69, 92, 115

23 is a Prime number because only 1x23 will equal 23. Therfore it has no factors besides 1 and 23, and it is not a common multiple of any number.

23 only has one proper factor which is 1

23 is and odd number because it does not divide up by 2 evenly. And it ends with 3 which is an odd number.
