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.
It is divisible by 2, 3, 4, 6 and 9.
3 <><><> 3 is only divisible by 1 and itself. whereas 4 and 10 are divisible by other numbers. 4 is divisible by 1,2,4. 10 is divisible by 1,2,5,10 <><><> A prime number is a number that is evenly divisible only by itself and one. Therefore, 3 is the prime number. 4 is divisible by 1, 2, and 4. 10 is divisible by 1, 2, 5, and 10. Three cannot be divided evenly by any other whole number. So, 3 is the prime number.
as 9 is made of 3 times 3 so any number (such as 90) which is divisible by 9 will also be divisible by 3 and the answer will be 3 times bigger so 90/9 is 10 then 90/3 = 30 which is 10 x 3 Example: same for any number that is divisible by 14 will also be divisible by 7 (or also 2) as 14 = 7 x 2 or divisible by say 50 is also divisible by 5 or 10 as 50 = 5 x 10 and so on ...
2, 5, and 10 . . . Yes. 3 and 9 . . . . . . No.
3720 is even, so it is divisible by 2. The digits in 3720 add up to a multiple of 3, so it is divisible by 3. The units digit in 3720 is 0, so it is divisible by both 5 and 10. 3720 is divisible by both 2 and 3, so it is divisible by 6. The digits of 3720 do not add up to a multiple of 9, so it is NOT divisible by 9. Remember these tricks. Super useful. :)
Only 3 and 9 are divisible by 405.
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.
To find out if a number is divisible by 3 add up all it's digest and check if the total is divisible by 3. to check if a number is divisible by 2 check if the last digit is divisible by 2. So one such number is 405.
Yes, 405 is divisible by 1, 3 , 5, 9 , 15, 27, 45, 81, 135, 405.
405 is divisible by: 1, 3, 5, 9, 15, 27, 45, 81, 135, 405.
It is divisible by 2 and 3. It isn't divisible by 5 and 10.
810/2 = 405 810/3 = 270 * 810/4 = 202.5 810/5 = 162 810/6 = 135 810/9 = 90 810/10 = 81 so 810 is divisible by 2 3 5 6 9 10 but not by 4
It is evenly divisible by 2 and 10 but not by 3 and 9.
Yes, it is divisible by 2, 3 and 9, but is not exactly divisible by 5 or 10.
9 is divisible by 3 10 is divisible by 2, 5 and 10. Everything else, no.
20 is divisible by 2, 5 and 10. It is not exactly divisible by 3 or 9.
It is divisible by 2, 5 and 10, but not 3 and 9.
