What Does It Mean for a Number to Be Divisible by Another Number?

A number is divisible by another number if it can be divided evenly without leaving a remainder. For example, 12 is divisible by 3 because 12 / 3 = 4 with no remainder.

In other words, a number is divisible by another number if the quotient (result of dividing) is an integer.

For example, 20 is divisible by 5 because 20 / 5 = 4 with no remainder.

Here are some examples of divisibility rules:

* 2 is divisible by 1 and 2 (all numbers are divisible by 1 and themselves)
* 3 is divisible by 1 and 3 (all numbers are divisible by 1 and themselves)
* 4 is divisible by 2 (any even number is divisible by 2)
* 5 is divisible by 5 (any number ending in 0 or 5 is divisible by 5)
* 6 is divisible by 2 and 3 (any number ending in 0, 2, 4, 6, or 8 is divisible by 2 and 3)

To determine if a number is divisible by another number, you can use these rules or perform long division to see if there is a remainder.
