The numbers that can divide 648 evenly, using the divisibility tests, include <u>1, 2, 3, 4, 6, 8, 9, 12, and 18</u> and some multiples of any two numbers.
<h3>What is the divisibility test?</h3>
A divisibility test is performed to identify whether a number can be divided evenly by a fixed divisor without a remainder and without actually performing the division process.
<u>Divisibility by 1</u>: Every number is divisible by 1 = 648 (648/1).
<u>Divisibility by 2</u>: 648 is an even number and divisible by 2 = 324.
<u>Divisibility by 3</u>: Sum the digits (18). 18 is divisible by 3 = 6 (18/3).
<u>Divisibility by 4</u>: The last two digits (4 and 8) form a number (12) that is divisible by 4
<u>Divisibility by 6</u>: It is divisible by 2 and by 3
<u>Divisibility by 8</u>: If the hundreds digit is even, the number formed by the last two digits must be divisible by 8.
<u>Divisibility by 9</u>: Sum the digits (18). 18 is divisible by 9
<u>Divisibility by 12</u>: 648 is divisible by 3 and by 4.
<u>Divisibility by 18</u>: 648 is divisible by 2 and by 9.
