running product finder

world's simplest integer tool

This online utility calculates the running product of several integers and displays the step-by-step multiplication process in the output. You can load the input integer data in any format and quickly adjust the delimiter character in the options. You can also use the skip-zero option to avoid the product turning into zero if any of the integers in the data is zero. Created by math nerds from team Browserling.

What is a running product finder?

With this browser-based program, you can find the running product (also known as the cumulative product) of multiple integer values. The program accepts any number of integers in any format as the input. It can be a vertical list, a sequence of integers, or even plain text with integers in it. If the "Smart Integer Detection" option is enabled, the program will scan the input data and extract all integers via its intelligent integer detection algorithm. By switching to the "Custom Integer Separation" option, you can manually specify a character that separates the integers in the input list. For example, if the input integers are comma-separated "10, 20, 30", then you can enter the comma "," in this option, or if the input is semicolon-separated "10; 20; 30", then you can enter the semicolon ";". The running product differs from the regular integer product in that it accumulates the intermediate results of the multiplication at every step of the computation and displays these intermediate partial products on the screen. For example, the regular product of integers 2, 4, 5, 6 is a single value and looks like this: 2×4×5×6 = 240 but the running product has four values: 2, 8, 40, 240. This is because the sequence starts with the integer 2, then it's multiplied by the second integer 2×4 = 8, then by the third 2×4×5 = 40, and then by the fourth 2×4×5×6 = 240. The integers 2, 8, 40, and 240 are cumulative (or intermediate) values of the computation. As you can see, the next integer is always multiplied by all the previous integers. If at any stage of the computation the value 0 is encountered, then all the following products (and the entire product) turns into 0. To prevent this zero result, use the "Avoid Zero Result" option that will skip all 0's in the input. You can also add position numbers of cumulative products by enabling the "Print Product Counter" option and view the factors contributing to each partial product by activating the "Print Product Multipliers" option. Integerabulous!

Increasing Running Product

This example calculates the running product of the first ten positive even integers. As there are no negative integers or zero values in the input, the partial products increase with each step. All partial results are displayed on individual lines and the last value is the total product of the entire multiplication.

Avoid Zeros

In this example, there are unwanted zero values among the integers. If we carried out the multiplication, then at the third integer it would turn zero and never change. To avoid that, we enable the "Avoid Zero Product" mode. Now all zeros are skipped and only non-zero values are used in the computation. We also insert the ";" symbol in the separator option because the input integers use the semicolon character as the delimiter character.

7; -4; 0; -3; -9; 5; 6; -4; 8; -4; 10; -1
7 -28 -28 84 -756 -3780 -22680 90720 725760 -2903040 -29030400 29030400

Weekly Squat Program

In this example, we decided to create a weekly at-home workout program for squats. As we're just starting, we'll do just two squats on the first day and then double the number of squats every next day. With the running product algorithm, we can examine the progress of training day after day and quickly see the exact number of squats we'll do every day. It turns out by the seventh day, we'll be doing 128 squats. Ouch!

Sunday: 2, Monday: 2, Tuesday: 2, Wednesday: 2, Thursday: 2, Friday: 2, Saturday: 2
1: 2 2: 4 3: 8 4: 16 5: 32 6: 64 7: 128

Integers Mixed with Textual Data

In this example, we copied a text fragment from a chapter on calculating cubes from a mathematical textbook. As the integers are mixed together with textual data in the input, we use the "Clever Integer Detection" option to separate the integers from text. As we're calculating a cube of the integer 7, we also show the square of the integer 7 by printing the product factors on the screen.

The cube of a number is the result of multiplying that number three times, for example 7 × 7 × 7.
7 (7) 49 (7 × 7) 343 (7 × 7 × 7)
