Answer:

7295

Step-by-step explanation:

The first thing we can do is rule out any numbers that cannot be divided by 5. Any number that ends in a 0 or a 5 can, so 627 cannot be. The next thing we do is use the division rule for dividing by 3. The rule states that if you add up the digits of a number, and it is divisible by 3, then so is that number.

2+8+5= 15 (multiple of 3)

5+4+9+0=18 (multiple of 3)

7+2+9+5=23 (not a multiple of 3)

4+3+6+9+5=27 (multiple of 3)

Hope you have a great day!
