Question

determine the largest 3 digit number which exactly divisible by 4,2,9 (maths)​

Answer 1

Answer:

Step-by-step explanation:

1. We know the divisibility rule for 4:

Check the last two digits are a multiple of 4 or if the last two digits are 00

Here, 996 is divisible by 4 because the last two digits are multiple of 4.

So, 996 is the largest 3 digit number exactly divisible by 4.

2.We know the divisibility rule for 2:

Always check the last digit end with 0,2,4,6 or 8.

Here, 848 is the largest 3 digit number exactly divisible by 2.

3. let’s start with the largest three digit number, and check to see how far off it is.

999 divided by 9 has a remainder of… zero. Hey, that’s it.

Unless.

The largest 3 digit number is 999. This number is divisible by 9 because

999/9=111 ; if using divisibility rule for 9, 9+9+9=27, and 27 /9=3, then 999 is

divisible by 9.
