Answer 2

Numbers

It is needed to find the smallest number which is exactly divisible by all numbers froms 1 to 9.

For finding the least numbers , LCM of all numbers will be.

$1=1\\2=2\times1\\3=3\times1\\4=2\times2\times1\\5=5\times1\\6=3\times2\times1\\7=7\times1\\8=2\times2\times2\times1\\9=3\times3\times1$

hence, the LCM of these numbers will be $1\times2\times2\times2\times3\times3\times5\times7=2520$

So the least number divisible by all numbers from 1 to 9 is 2520.
