Did you ever wonder how people could tell if something was divisible by a number just by looking at it? These rules are how they do it. Memorize a few simple rules and simplifying Created Date: 20120906071929Z 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 simple as checking to see if its last digit is 2, 4, 6, 8 or 0. Multiple divisibility rules applied to the same number in this way can help quickly determine its prime factorization without Divisibility rules poster great for a math word wall or as a reference in a student's binder. Woks great to help students reduce fractions, find greatest common factors and lowest common multiples and prime factors.

(9, 18, 27, 45 , - can use the hundreds chart to check) Example: 342 = 3+4+2 = 9 * A number is divisible by 10 if it ends with a 0. Directions: Cut on the dotted lines and glue the notes on the inside of the foldable rules of divisibility page. If they can do this then they cross off the number on the game board. For example, the cards 2, 4, 5 can be arranged as 524 which is divisible by 2, or as 245 which is divisible by 5. In each turn a player may only cross off one number, in the example the player could cross off either 2 or 5. The divisibility rules are on the game board page. Divisibility Rules .

Simple divisibility rules are given for the 1st 1000 prime numbers. PACS numbers: 02.10.Lh This paper presents simple divisibility rules for the 1st 1000 prime numbers. With two exceptions, the rules in question are based on the A divisibility rule is a shorthand way of determining whether a given integer is divisible by a fixed divisor without performing the division, usually by examining its digits. Although there are divisibility tests for numbers in any radix, or base, a
