CISCE: Class 6
Rule
Look at the last three digits of the number.
If these digits form a number that is divisible by 8, the whole number is divisible by 8.
CISCE: Class 6
Step-by-Step Explanation
CISCE: Class 6
Examples
1. 5,408:
The last 3 digits are 408.
408 ÷ 8 = 51
So, 5408 is divisible by 8.
2. 18,824:
The last 3 digits are 824.
824 ÷ 8 = 103
So, 18824 is divisible by 8.
CISCE: Class 6
Real-Life Application
Imagine you have 1,000 candies and want to pack them into boxes of 8, with no candy left over.
1,000 ÷ 8 = 125, remainder 0.
So, all candies can be packed evenly!
CISCE: Class 6
Key Points Summary
-
Always check the last three digits.
-
For numbers less than 1,000, use the whole number.
-
Numbers ending in “000” (like 12,000) are always divisible by 8.
