First find the least common multiple (LCM) of all the integers 1 to 16. One way to find the LCM's is to use prime factorization.
1 = 1
2 = 2
3 = 3
4 = 2 * 2
5 = 5
6 = 2 * 3
7 = 7
8 = 2 * 2 * 2
9 = 3 * 3
10 = 2 * 5
11 = 11
12 = 2 * 2 * 3
13 = 13
14 = 2 * 7
15 = 3 * 5
16 = 2 * 2 * 2 * 2
The LCM of all these will be the product of all the different factors. When a factor appears more than once in list of factors, use the the longest string of this factor. So, LCM = 1*2*2*2*2*3*3*5*7*11*13 = 720720.
