Answer:
2400
5400
8400
Explanation:
You need to know the Divisibility Rules for 3, 5, and 8.
For 3: If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.
For 5: If the last number is either 0 or 5, the entire number is divisible by 5.
For 8: If the last three digits of a whole number are divisible by 8, then the entire number is divisible by 8.
You can put 0 to the end to meet the requirements of the divisibility rule of 5,
so it should be like _ _ _ 0
for 8, you can use 400 so it should look like _ 400
For 3, the sum of the digits needs to be divisible by 3
if we say X to the first digit the sum of the digits is x+4
we can use 6 and 9, so x can be 2, 5, and 8.
Therefore we have:
2400
5400
8400
