To get started with multiples, the easiest way is just to add a number to itself over and over again. For instance, if you want to find the multiples of 3110 using this method, you could start at 3110, and keep adding 3110 over and over: 3110, 6220, 9330, 12440, and so on. Each of these numbers is a multiple of 3110. Usually, this method works with numbers that are easily added to itself. As you get into larger numbers, it can become difficult to continue adding.
Another way to do this, as discussed above, is to use choose any number and multiply it by 3110. To find the first few multiples of 3110, you could just multiply the 3110 by 1, then 2, then 3, and so on, until you have as many multiples as you would like.
There are an endless number of multiples! You can keep using either of these methods to find as many multiples as you would like.
