To determine if 405 is divisible by 2, we check if it is even, which it is not, so it is not divisible by 2. To check for divisibility by 3, we sum the digits of 405 (4+0+5=9), and since this sum is divisible by 3, 405 is divisible by 3. For divisibility by 5, we check if the last digit is 0 or 5, which it is, so 405 is divisible by 5. To check for divisibility by 9, we sum the digits again (4+0+5=9), and since this sum is divisible by 9, 405 is divisible by 9. Lastly, for divisibility by 10, we check if the number ends in 0, which it does, so 405 is divisible by 10.
The nearest ten to 405 is 410. When rounding to the nearest ten, we look at the digit in the tens place, which in this case is 0. Since 0 is less than 5, we round down to the nearest ten, which is 400. The next multiple of ten after 400 is 410, making it the nearest ten to 405.
The positive integer factors of 405 are: 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
