divisibility

One quantity is said to be '''divisible''' by another quantity if there is an integer factor which, when multiplied by the second quantity, gives exactly the first quantity.

For example, the number 54 is divisible by 7 because there exists an integer factor (in this case, 8) which, when multiplied by 7, gives us exactly 54.

Following this rule, we can say that the number 12 is divisible by the numbers 1, 2, 3, 4, 6 and 12.

Note that all integers are divisible by one. All even integers are divisible by 2. And all integers are divisible by themselves.

In computer calculations, x is divisible by y if the following expression is True:

x mod y = 0
