What is the smallest number whose factors are 2 4 and 9?

Oh, dude, are we playing math games now? The smallest number that has 2, 4, and 9 as factors is actually just their product, which is 72. So, like, if you need to divide something equally between 2, 4, and 9 people, you're gonna need 72 of those things. Math can be fun, right?
