In math, a number is said to be divisible by another number if the remainder after division is 0. Learn the important divisibility rules along with examples.
Use the definition of divisibility to show that given any integers \(a\), \(b\), and \(c\), where \(a\neq0\), if \(a\mid b\) and \(a\mid c\), then \(a\mid(sb^2+tc^2)\) for any integers \(s\) and \(t\).
Divisibility rules are a set of general rules that are often used to determine whether or not a number is absolutely divisible by another number. Note that “divisible by” means a number divides the given number without any remainder, and the answer is a whole number.
The Divisibility Rules. These rules let you test if one number is divisible by another, without having to do too much calculation!
The first section contains 5 sheets and involves using the divisibility rules to fill in a table to say whether numbers are divisible by different digits. The second section contains 2 puzzles - the aim of each puzzle is to use the clues to work out the correct solution from 8 possible answers.
The Rules of Divisibility. Lessons with videos, examples, solutions and stories to help students learn the Divisibility Rules. The multiple of a number is always divisible by the number. The word “divisible” means that it can be divided exactly. 144 ÷ 4 = 36 (remainder = 0).
