// Question: What is the smallest number divisible by each of the
//           numbers 1 to 20?
//
// I factorize each of the numbers 1 to 20.  For example, 12=2*2*3.
// This factorization can be represented by a histogram (2*2 3*1).  If
// a number is evenly divisible by 20, it must be a product of at
// least two 2's and a 3.  So I accumulate each factorization into a
// histogram by the following rule: if the factorization contains two
// 2's, the accumulation must contain at least two 2's.  Then the
// final result is the product of numbers in the accumulation.
