How to Generate the Multiples of a Number - dummies

By Mark Zegarelli

Generating the multiples of a number is easier than generating the factors: Just multiply the number by 1, 2, 3, and so forth. But unlike the factors of a number — which are always less than the number itself — the multiples of a number (except 0 and the number itself) are greater than that number. Therefore, you can never write down all the multiples of any number (except 0).

Sample questions

  1. Find the first six (positive) multiples of 4.

    4, 8, 12, 16, 20, 24. Write down the number 4 and keep adding 4 to it until you’ve written down six numbers.

  2. List the first six multiples of 12.

    12, 24, 36, 48, 60, 72. Write down 12 and keep adding 12 to it until you’ve written down six numbers.

Practice questions

  1. Write the first six multiples of 5.

  2. Generate the first six multiples of 7.

  3. List the first ten multiples of 8.

  4. Write the first six multiples of 15.

Following are the answers to the practice questions:

  1. The first six multiples of 5 are 5, 10, 15, 20, 25, and 30. Write down the number 5 and keep adding 5 to it until you’ve written six numbers.

  2. The first six multiples of 7 are 7, 14, 21, 28, 35, and 42.

  3. The first ten multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, and 80.

  4. The first six multiples of 15 are 15, 30, 45, 60, 75, and 90.
