2013 / 13 = 154.84615384615384615384615384615
round down to 154
13 x 13 = 169
2013 / 169 = 11.911242603550295857988165680473
round down to 11
13, 26, 39, ... 2002
but these include 169, 338, 507, ... 1859 notice this set is included in the above set.
so there are 154 numbers that are multiples of 13
there are 11 numbers that are multiples of 169 (each includes 2 factors of 13) but they are counted in the 154 factors above... so the answer is
154 + 11x2 - 11 = =154 + 11 = 165

How do you determine the number of factors a factorial of a number has?
Suppose you're talking about N factorial. For an example, we'll let N be 20.For each prime number p, repeatedly divide N by p, discarding the remainder. Add up the answers.20/2 = 10, 10/2 = 5, 5/2 = 2, 2/2 = 1. 10+5+2+1 = 18.20/3 = 6, 6/3 = 2. 6+2 = 8.20/5 = 420/7 = 220/11 = 120/13 = 120/17 = 120/19 = 1Now add 1 to each of these results: 19,9,5,3,2,2,2,2.Now multiply these numbers. 19x9x5x3x2x2x2x2 = 41040.This is how many factors the factorial has. 20! has 41040 factors. (This includes both 1 and the factorial itself. Subtract 1 if you're only counting the proper factors.)The proof is left as an exercise for the reader.
