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.
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).
PRACTICE QUESTIONS ON DIVISIBILITY RULES. Question 1 : If the number 517*324 is completely divisible by 3, then the smallest whole number in the place of * will be ? (A) 2 (B) 3 (C) 4 (D) 5. Solution : Divisibility rule for 3 :
Definition of Divisbility. 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.
