Well, let's take a moment to look at this question. To see if a number is divisible by 3, you can add up the digits and see if that sum is divisible by 3. For 780, 7 + 8 + 0 = 15, which is divisible by 3. But for 320, 3 + 2 + 0 = 5, which is not divisible by 3. So, 780 is divisible by 3.

Now, to check if a number is divisible by 5, you can see if the last digit is 0 or 5. In this case, 780 ends in 0, so it's divisible by 5. However, 320 does not end in 0 or 5, so it's not divisible by 5. So, 780 is divisible by both 3 and 5, while 320 is only divisible by 5.
