And then I read it to Kiir.  The problem is to find the smallest number evenly divisble by all the numbers from 1-20.  We decided that it didn’t mean at the same time, since that’s factorial

And then … *sigh* I felt compelled to find the answer.  My answer and logic after the break

Basically what I did was try to figure out, roughly and quickly, what the minimum value would be.

I took 20, because it gave me 20 10 5 4 2 1, good start.  Then I took 9, which gives me 9 and 3.

From those two 6 15 12 and 18 “fall out” (the combination of values, 3*2, 3*5, 3*4, 9*2)

Then I needed the prime numbers (7 11 13 17 19) because they can’t be dodged.  They’re prime, after all.

After that I’m missing 16 and 8, so I multiplied by 4 (combined with the 2 and 4 from the 20 to give 8 and 16).

Then I realized that I maybe didn’t need the 20, so I took the primes, 5 9 and 16.

Both answers gave me 232,792,560 (well, the second way gave me a smaller number, but that was because I forgot the 7)

So … that’s my answer.
