2520
because 8 x 9 x 5 x 7 = 2520
Since the LCM of a group of numbers is also the LCM of the LCM of a smaller group of numbers, the LCM of 2,4, and 8 is 8. The LCM of 3 and 9 is 9. So, the LCM of 9 and 8 is 72. 72 divided by 6 leaves no remainder, so you can ignore it. Since 5 and 7 are prime, you can then multiply them into 72, which yield 2520. 10 also goes into 2520, so you can also ignore it.
Try it... It works for all the numbers.
