In order for a number to be divisible by 6 and 9, it has to satisfy two characteristics. 1) it has to be even. 2) the sum of the individual digits must be a multiple of 9 (9, 18, 27, etc). For example, let's see if 126 works. 126 = even 1 + 2 + 6 = 9 Therefore, it is divisible by 6 and 9.

Is 5890 divisible by 2 3 6 9 5 10?
Test of divisibility by 2:If a number is even then the number can be evenly divided by 2.5890 is an even number so, it is divisible by 2.Test of divisibility by 3:A number is divisible by 3 if the sum of digits of the number is a multiple of 3.Sum of digits = 5+8+9+0 = 22, which is not a multiple of 3.So, 5890 is not divisible by 3.Test of divisibility by 6:In order to check if a number is divisible by 6, we have to check if it is divisible by both 2 and 3 because 6 = 2x3.As we have seen above that 5890 is not divisible by 3 so, 5890 fails to pass the divisibility test by 6.Test of divisibility by 9:If the sum of digits of a number is divisible by 9 then the number is divisible by 9.Sum of digits = 5+8+9+0 = 22, which is not a multiple of 9.So, 5890 is not divisible by 9.Test of divisibility by 5:If the last digit of a number is 0 or 5, then it is divisible by 5.It is clear that 5890 is divisible by 5.Test of divisibility by 10:If the last digit of a number is 0, then the number is divisible by 10.It is clear that 5890 is divisible by 10 as the last digit is 0.

Is 3705 divisible by 9?
NO!!! To test divisibility by '9' add the digits. If the ddigits sum to '9' , then the number is divisible by '9' . Hence 3705 ; 3 + 7 + 0 + 5 = 15 = 1 + 5 = 6 So it does not add to '9' , so it is not divisible by '9'.
