For a beginner, 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 3533, you could start at 3533, and keep adding 3533 over and over: 3533, 7066, 10599, 14132, and so on. Each of these numbers is a multiple of 3533. 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 3533, you could just multiply 3533 by each number in sequence, first multiplying by 1, then 2, then 3, and so on, which we will outline below.
