Answer 2

Answer:

The largest 5 digit number exactly divisible by 40 is 99960.

Step-by-step explanation:

A number is divisible by 40, if the number ends with 0; i.e. the last digit must be 0.

So in a five digit number, the last number that is the 5th number should be 0

Out of the 4 remaining digits, the last 2 digits must be divisible by 4. [Divisibility rule of 4.]

According the largest 2digit number that can be divided by 4 is 96.

Thus, the last 3 digits of the 5 digit number is 960.

And, the largest 5-digit number which exactly divisible by 40 is 99960.
