Divisibility rule of 4: Divisibility rules are shortcuts to

Divisibility rules are shortcuts to determine if a number is divisible by another number without performing the actual division, usually by examining the digits of the given number. A number is divisible by 4 if the number is formed by its digits in ten’s place and unit’s place (i.e. the last two digits on its extreme right side) is divisible by 4 . Consider the following numbers which are divisible by 4 or which are divisible by 4 , using the test of The divisibility rule of 4 states that a number is divisible by 4 completely if its last two digits are zero or multiples of 4 . The divisibility rule of 4 remains same for all digit numbers. 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 ...
