Role of Digital Root in Number Theory

Abstract

In Vedic mathematics, digital root of a number is known as Beejank. Before the development of computer devices, the idea was used to check the results of mathematical operations. In this paper, we highlight the properties of digital root of a number and some results of digital roots. There are many interesting properties of digital root of a number. Perfect square number and a perfect cube number have specific digital roots. In modern mathematics, digital roots make partition of the set of natural numbers. Nowadays digital root of a number has many applications in generation of random sequence of numbers.
