Every number is divisible by any non-zero number. Furthermore, 405 is evenly divisible by both 3 and 9.
Multiples of 9 and 6 are also divisible by three, the reverse is not true. 15 is divisible by 3, but not 6 or 9. 27 is divisible by 3 and 9, but not 6. 12 is divisible by 3 and 6, but not 9. 54 is divisible by 3, 6 and 9.
Using the tests for divisibility:Divisible by 3:Add the digits and if the sum is divisible by 3, so is the original number: 6 + 8 + 4 = 18 which is divisible by 3, so 684 is divisible by 3Divisible by 6:Number is divisible by 2 and 3: Divisible by 2:If the number is even (last digit divisible by 2), then the whole number is divisible by 2. 684 is even so 684 is divisible by 2.Divisible by 3:Already shown above to be divisible by 3. 684 is divisible by both 2 & 3 so 684 is divisible by 6Divisible by 9:Add the digits and if the sum is divisible by 9, so is the original number: 6 + 8 + 4 = 18 which is divisible by 9, so 684 is divisible by 9Thus 684 is divisible by all 3, 6 & 9.
Numbers such as 135, 270, 405, and other multiples of 135.
Multiples of 45 in that range include 405, 450, 495, 540, 585, 630, 675, 720, 765, 810, 855 and 900
Only 3 and 9 are divisible by 405.
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.
405 is divisible by: 1, 3, 5, 9, 15, 27, 45, 81, 135, 405.
Every number is divisible by any non-zero number. Furthermore, 405 is evenly divisible by both 3 and 9.
405 = 3 x 135 = 3 x 3 x 45 = 3 x 3 x 3 x 15 = 3 x 3 x 3 x 3 x 5, so it's divisible by 1, 3, 5, 9, 15, 27, 45, 81, 135 and 405 It is divisible by 9 because its digits add up to 9
yes
Try dividing on a calculator, for example, 405 / 2, 405 / 3, etc. If you get a whole number (no digits after the decimal point), it's divisible. Otherwise it isn't.
The LCM is 405.
All numbers divisible by 3 are NOT divisible by 9. As an example, 6, which is divisible by 3, is not divisible by 9. However, all numbers divisible by 9 are also divisible by 3 because 9 is divisible by 3.
9 is divisible by both 3 and 9
1, 3, 5, 9, 15, 25, 27, 45, 75, 81, 135, 225, 405, 675, 2025
Three is divisible by 3 and 9.
