621 is divisible by these numbers: 1, 3, 9, 23, 27, 69, 207, 621.
To determine if 621 is divisible by 2, we look at the last digit which is 1, and since it is odd, 621 is not divisible by 2. To check divisibility by 3, we sum the digits: 6 + 2 + 1 = 9, which is divisible by 3, so 621 is divisible by 3. For divisibility by 4, we examine the last two digits, which are 21, and since 21 is not divisible by 4, 621 is not divisible by 4. Since the last digit is not 0 or 5, 621 is not divisible by 5. 621 is not divisible by 6 as it is not divisible by both 2 and 3 simultaneously. Lastly, since 621 ends in 1, it is not divisible by 10.
yes
As 4 is less than 621, 4 is not divisible by 621. Nor is 621 divisible by 4: 4 is even and all multiples of 4 are even, 621 is odd and so cannot be a multiple of 4. To check divisibility by 4, if the the last 2 digits are divisible by 4, the original number is divisible by 4. For 621, the last 2 digits are 21 and 21 is not divisible by 4, thus 621 is not divisible by 4; nor is 622 since the last 2 digits 22 is not divisible by 4.

621 is divisible by these numbers: 1, 3, 9, 23, 27, 69, 207, 621.
In order for a number to be divisible by 6, it must be divisible by both 3 and 2. 621 is divisible by 3, but not by 2. In other words, 6 will not go into 621 evenly. The answer will be a decimal.
yes
621 is divisible by 9?
