Digital root is the value of adding all the digits of a number together until you get a single-digit number. For example, if we wanted to find the digital root of 6,531, we would do the following: 6 + 5 + 3 + 1 = 15. Then we do it again: 1 + 5 = 6. 6 is the digital root of 6,531.

How to Calculate Digital Root

Digital root is often considered to be an easy calculation and almost fun. The way you do it is simple. You will add together the digits in a number individually. You do this until there is only a single digit value left. That single digit that you have left is the digital root.

Understanding Your Results

The digital root result will always be a single digital number. This number is always at least 1 and no larger than 9. It will also always be a whole number, the digital root can not be a decimal.

We will enter 1,874 into the lone number field and hit calculate to get an answer of 2. Finally, we need to find the digital root of 8. We simply enter 8 into the field and hit calculate and get a digital root of 8.

Digital Root - Frequently Asked Questions

Digital root is simply adding the digits of a number together until we get a single-digit number left over. Let's try it with 489. First, we do: 4 + 8 + 9 = 21. Then we do it again: 2 + 1 = 3. That means 3 is the digital root of 489.

The digital root of 1,234 is 1. The math is: 1 + 2 + 3 + 4 = 10, then we do 1 + 0 to get an answer of 1.

Digital root does not seem like it may have many applications, but there are very niche applications for this concept. Namely, number theory and cryptography rely on digital root in some cases, making it likely the two most common applications for this concept.

No, digital root cannot be negative since it involves a positive integer and the addition of the digits in it.
