The method to check divisibiity by '9' is the add the digits. If the addition sum to '9' , then the number is divisible by '9'. Hence. 998876 ; 9+9+8+8+7+6 = 47 ; 4 + 7 = 11 ; 1+ 1 = 2 Do NOT divisible by '9'.
No. If the sum of the digits of a number is divisible by 3 then the number will be also. In this case, 9+9+8+8+7+6=47 which is not divisible by 3.
No. 47 is a prime number and is only divisible by 1 and itself.
Yes. 423 is divisible by 1, 3, 9, 47, 141, 423.
As 47 is a prime number, the only possible factors are 1 and 47. 2728 is not divisible by 47, so the only common factor is 1.
No.
no
No. it is not
47 is a prime number and is divisible by 1 and 47 only. 51 is divisible by 1, 3, 17, 51.
No. 47 is not evenly divisible by 11.
As 235 is ending by a 5 then it is divisible by 5 As 235 is not even it is not divisible by 2 As 2+3+5 is not divisible by 3, 235 is not divisible by 3 235/5 = 47 47 is prime so 235 = 5 * 47 and there's no other way to factorize it
