### Divisibility in Whole Numbers

When dividing a whole number, dividend, by another whole number, divisor, the result is quotient and remainder. The remainder is 0, or in other words, the divisor divides the dividend without a remainder. This basic property leads to understanding all the following

•  odd and even numbers

•  prime and composite numbers

•  factors and multiples of a number

•  LCM and HCF

•  Divisibility tests

This lesson provides breathtakingly simple and intuitive explanations to the above topics. Especially, the divisibility tests are explained in a simple-thought-process to understand why the procedure works.
