How can I determine if a number is divisible by 8?

To determine if a number is divisible by 8, you can follow a simple rule: a number is divisible by 8 if the last three digits of the number form a number that is divisible by 8.

Here’s a step-by-step guide to help you:

1. Identify the last three digits: Start by looking at the last three digits of the number. For example, if you have the number 52,468, the last three digits are 468.
2. Check divisibility: Now, check if this three-digit number is divisible by 8. You can do this by dividing it by 8. If you get a whole number (no remainder), then the entire original number is divisible by 8.
3. Perform the calculation: For our example with 468, you would perform the division: 468 ÷ 8 = 58.5. Since this result is not a whole number, 52,468 is not divisible by 8.
4. Try a different example: Let’s check 1,024. The last three digits are 024. Now perform the division: 24 ÷ 8 = 3. Since this is a whole number, we can conclude that 1,024 is divisible by 8.

In summary, just focus on the last three digits of your number and see if that chunk can be divided by 8 without leaving a remainder. This method simplifies the process and helps you quickly determine divisibility by 8!
