This browser-based tool multiplies all digits in an integer and prints their product in the output. You can choose between two multiplication modes – single-pass mode that simply multiplies all digits together or multi-pass mode that multiplies all digits together recursively until a single-digit root value is left. You can also skip zeros during the multiplication process to avoid the zero product. Created by math nerds from team Browserling.
With this online utility, you can multiply all the digits of an integer and find their product. For example, if the input contains the integer 1237, then after multiplying its digits 1×2×3×8, the output 48 will be produced. The input may contain arbitrary large integers with any number of digits. If the "Repeated Digital Product" option is disabled (by default it's disabled), the program prints this one value and stops. If the "Repeated Digital Product" option is enabled, then the program restarts the algorithm and recursively applies it to the previous product. For example, 1×2×3×8 = 48, then 4×8 = 32, then 3×2 = 6. When a one-digit value is reached, the algorithm stops and displays all intermediate results on the screen. The single-digit integer resulting from repeated multiplications is called the repeated digital root. If there's at least one occurrence of a zero in integer's digits, the entire product becomes zero. If you use the "Skip Zeros" option, then it skips all zero factors and the result is non-zero. Integerabulous!
In this example, we calculate the digit product of several integers in parallel. Each input integer is on its own line and each result is also on its own line. If there's at least one zero in the integer, then the entire product is turned to zero (see the integer on line four). The signs of integers are preserved in the results (see integers on lines two and three).
In this example, we have enabled the "Repeated Digital Product" option that iteratively calculates the multiplicative digit root for seven different integer values. The program automatically determines how many times to apply the multiplication function on the results to get a one-digit value as the final product.
This example contains integers that each have one or more zero-digits. For such integers, the product of digits is always zero. To get a non-zero result, we use the skip zero digits option. It drops zeros from the input and the multiplication algorithm safely produces a non-zero result.
You can pass input to this tool via ?input query argument and it will automatically compute output. Here's how to type it in your browser's address bar. Click to try!
