In this section, we learn about the divisibility rules for the numbers two through twelve. When we say a number is “divisible by” another,
this means there is no remainder involved in the division. These rules allow us to determine if a given number is divisible by one of the numbers on the list: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12.
Having this tool, allows us to factor large numbers pretty quickly. For example, the rule for divisibility by ten, tells us that a number is divisible by ten if the final digit is a zero. If we see a
large number such as: 1050, we immediately know it is divisible by ten, or in other words, ten is one of its factors.
