Friends,

How do you check a number is divisible by 4?

Take first two digits(units place and tens place) and divide with 4. If the two digit number is divisible by 4, the number is divisible by 4. 

Let me take one example

Ex1 : 2345672
step 1 : take first two digits. Here it is 72
step 2 : Is 72 divisible by 4?  Yes. So 2345672 is divisible by 4.

Find the number 56784345644 divisible by 4 or not?

How do you check a number is divisible by 8?
Take first three digits(units place, tens place and hundreds place) and divide with 8. If the three digit number is divisible by 8, the number is divisible by 8.

Let me take above example

Ex : 2345672
step 1 : take first three digits. Here it is 672
step 2 : Is 672 divisible by 8?  Yes. So 2345672 is divisible by 8.
