Examples and detailed solutions on the divisibility of whole numbers are presented. Questions and their solutions are also included.
A whole number n is divisible by another number m if the division n / m yields a remainder equal to 0. m is called the factor of n.
Example: 15 is divisible by 5 because 15 / 5 = 3 and remainder is equal to 0. Also 15 = 3 * 5. Both 3 and 5 are factors of 15. Also 15 / 3 = 5. 15 is also divisible by 3.
