Divisibility rules are rules that help us determine whether a number is divisible by another number or not. Learn rules, examples, and more.

A divisibility rule is a heuristic for determining whether a positive integer can be evenly divided by another (i.e. there is no remainder left over). For example, determining if a number is even is as …

Generally, a number is divisible by another if the quotient is a whole number (i.e. there is no remainder). There are also divisibility rules for testing whether a given number is divisible by specific integers. …

Learn divisibility rules with clear examples. A number is divisible by 2 if its last digit is even; or divisible by 3 if the sum of its digits is divisible by 3.

Divisibility tests for 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13, so you can tell if those numbers are factors of a given number or not without dividing, with video lessons, examples and step-by-step solutions.
