How this multiples calculator works
Enter a number and how many multiples you want. The calculator builds the list number × 1, number × 2, number × 3, and so on, up to the count you set. For 5 with the default count of 10, the list is 5, 10, 15, 20, 25, 30, 35, 40, 45, 50.
A multiple of a number is that number times a positive whole number. The first term is always 1 × the number, so the list for 9 begins 9, 18, 27, not 0. The How many multiples field starts at 10 and must be an integer from 1 to 50. A count of 6 for 12 gives 12, 24, 36, 48, 60, 72.
The Number box accepts any finite value. Decimals and negatives are multiplied the same way. 0.5 with a count of 5 is 0.5, 1, 1.5, 2, 2.5. −3 with a count of 4 is −3, −6, −9, −12. Zero is allowed, and every term is then 0. An empty Number box, a count outside 1–50, a decimal count, or a non-integer count shows the prompt “Enter valid values (count 1-50).”
This list is a times table for the number you type. 8 with a count of 10 is 8, 16, 24, 32, 40, 48, 56, 64, 72, 80. It is not a list of factors. Factors of 12 divide 12 evenly. Multiples of 12 grow by twelve: 12, 24, 36, 48.
