Question

Divisibility by 8 requires checking the last three digits of a number because 8 is evenly divisible by 2 and 4. If the last three digits of a number are divisible by 8, then the entire number is divisible by 8. This is a property of divisibility by 8.

Answer 1

To check if a number is divisible by 8, it is sufficient to check its last three digits. If the last three digits are divisible by 8, then the entire number is divisible by 8.

Step-by-step explanation:

Divisibility by 8 requires checking the last three digits of a number because 8 is evenly divisible by 2 and 4. If the last three digits of a number are divisible by 8, then the entire number is divisible by 8. For example, let's consider the number 4568. The last three digits are 568, which is divisible by 8 (since 568 ÷ 8 = 71). Therefore, the number 4568 is also divisible by 8.
