For a beginner, a math tutor suggests that you can find the multiples of a number by skip-counting to the next number. For Instance, if you want to find the multiples of 3990, you could start at 3990, and keep adding 3990 over and over: 3990, 7980, 11970, 15960, and so on. Each of these numbers is a multiple of 3990. Typically, this works best only for smaller numbers, as adding larger numbers together over and over can be difficult.
Another way to do this is to use multiplication. To find the first few multiples of 3990, you could just multiply 3990 by each number in sequence, first multiplying by 1, then 2, then 3, and so on, which we will outline below.
