If you have read the discussion on divisibility by 4, the proof for divisibility by 8 is somewhat similar. To know that the number is divisible by 4, we just have to look at the last two digits. In divisibility by 8, we look at the last three digits. For example, the number 10938648 is divisible by […]

## Proof of Divisibility By 6

After discussing divisibility by 5, we proceed to divisibility by 6. A number is divisible by 6 if (1) it is even (2) it is divisible by 3 The explanation to this is quite simple. First, if a number is even, then it is divisible by 2. Let n be that number. Since is even, […]

## The Proof of Divisibility by 4

We examine more about divisibility rules and see why they work. In this post, we discuss divisibility by 4. If you can recall, divisibility by 4 states that A number is divisible by 4 if the last two digits are divisible by 4. The last two digits in that rule means the tens and ones […]
