How can you determine if a number is divisible by 8

Question: How can you determine if a number is divisible by 8

Answer: 

A number is divisible by 8 if the last three digits of the number form a number that is divisible by 8.

Steps to check divisibility by 8:

1. Take the last three digits of the number.
2. Check if this three-digit number is divisible by 8.

Example 1:

• Number: 24,568
• Last three digits: 568
• Check: 568 ÷ 8 = 71 (exact division)
• ✅ 568 is divisible by 8, so 24,568 is divisible by 8.

Example 2:

• Number: 52,374
• Last three digits: 374
• Check: 374 ÷ 8 = 46.75 (not an integer)
• ❌ 374 is not divisible by 8, so 52,374 is not divisible by 8.

This rule works because 1000 is divisible by 8, so the divisibility of a number by 8 depends only on its last three digits.
