LCM Sudoku

In today's Sudoku, the clues between cells represent the least common multiple of the numbers contained in those cells.  For example, if the clue is 72, then we know the numbers must be (8,9) in some order, but if the clue is 6, then the numbers could be (1,6),(2,6),(3,6), or (2,3).

This first one is meant to be easy, so not all the clues listed are actually needed for a unique solution.

Here's a second one that takes a little more work to solve.
