And apply method 2
It works very well.

To find the lowest number that is divisible by 1, 2, 3, 4, 5, 6, 7, 8, and 9, you need to find their least common multiple (LCM). The LCM is the smallest number that all of these numbers can evenly divide into.

Here's how you can calculate it using method 2 from the website mentioned:

1. Visit the website http://www.helpwithfractions.com/least-common-denominator.html to access their calculator.
2. Look for "Method 2" on the webpage, which is likely a step-by-step explanation.
3. Enter the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 into the calculator.
4. Follow the instructions on the webpage to calculate the LCM using method 2.
5. The result will be the smallest number divisible by all the given numbers.

By using the LCM calculator on the website, you should be able to find the answer to your question easily.
