no both are divisible by 3
no. if you divided it by nine you would get a number with a big decimal. But is divisible by 5. (105/5=21)
3*21 = 63 so 63 is divisible by 3 7*9 = 63 so 63 is divisible by 7.
Nope - To be divisible by nine, the sum of the digits must also be divisible by 9 (the digits total 21). Additionally, since it's an odd number - it cannot be divided by 6 !
126 is divisible by 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.

1, 3, 7, 9, 21, 63
1, 63, 3, 21, 7, 9
3*21 = 63 so 63 is divisible by 3 7*9 = 63 so 63 is divisible by 7.
To check divisibility of 9, add the digits together. add the digits again if your answer has 2 or more digits. you should get 9 as the remaining digit to be divisible by 9. 4 + 0 + 8 + 9 = 21 2 + 1 = 3 So 4089 is not divisible by 9.

A Harshad number is a positive integer which is is divisible by the sum of its digits. There are many Harshad numbers, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 18 (1 + 8 = 9 and 18 is divisible by 9), 21 (2 + 1 = 3 and 21 is divisible by 3), and 24 ( 2 + 4 = 6 and 24 is divisible by 6).
it cannot be divisable by 5 and 9 but it can be divisable by 2,3,4,6,41,28,and 21
189 is divisible by: 1, 3, 7, 9, 21, 27, 63, 189.
No, it is divisible by: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
