Think of the chairs as arrays. The dimensions of the arrays give you the factors of 18.
18 Chairs into equal rows - 6 x 3 2 x 9 18 x 1
You can have: 1 row of 36 2 rows of 18 3 rows of 12 4 rows of 9 or 6 rows of 6, so in total there are 5 ways.
You can only do multiplation so a whole number is divisble by another whole number when the quotient is a whole number and the remainder is 0
There are 19 ways to do this.
If you are Canadian (no joke), there are 618(101559956668416) ways. If you are american, there are 518(3814697265652) ways. Hope this helps!

> 6.40237371 × 1015Actually, since there are four i's and two o's, the number of distinct permutations of the letters in "oversimplification" is 18!/(4!2!) = 133,382,785,536,000.

The number of ways is 18C5 = 18!/(5!*13!) = 8,568 ways.
if order of beads matters than you get 18P12= 8.892185702*1012. if order doesn't matter than it's 18C12= 18564 ways to arrange the beads.

You can arrange them in (20 x 19 x 18 x 17 x 16 x ..... 4 x 3 x 2) ways.That number is called "20 factorial", and written " 20! ".It's a big number ... bigger than my calculator can show exactly.Rounded to the nearest billion, it's2,432,902,008,000,000,000
