Methods for Finding Multiples: from a Math Tutor

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 641, you could start at 641, and keep adding 641 over and over: 641, 1282, 1923, 2564, and so on. Each of these numbers is a multiple of 641. 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 641, you could just multiply 641 by each number in sequence, first multiplying by 1, then 2, then 3, and so on, which we will outline below.

What are the Multiples of 641?

So, what are the multiples of 641? Let’s write it out using the multiplication method:

641×1=641641 × 1 = 641

641×2=1282641 × 2 = 1282

641×3=1923641 × 3 = 1923

641×4=2564641 × 4 = 2564

641×5=3205641 × 5 = 3205

641×6=3846641 × 6 = 3846

641×7=4487641 × 7 = 4487

641×8=5128641 × 8 = 5128

641×9=5769641 × 9 = 5769

641×10=6410641 × 10 = 6410

So, the first 10 multiples of 641 are: 641, 1282, 1923, 2564, 3205, 3846, 4487, 5128, 5769 and 6410.
