Answer 1

Step-by-step explanation:

1) not divisible by any of the numbers 2) divisible by 3 and 6 only 3) divisible by 3 and 9 4) divisible by 3 only A natural number is divisible by 3 if and only if the sum of it's digits is divisible by 3. Eg : 4) 3+7+4+6+1= 21 ; which is divisible by 3 A natural number is divisible by 9 if and only if the sum of it's digits is divisible by 9. Eg : 3) 1+4+3+0+1= 9 which is divisible by 9 A natural number is divisible by 6 only if the number is divisible by 2 and 3. For a no. to be divisible by 2 it must be an even no. and for the divisibility property of 3 refer above . Eg : 3) which is even (divisible by 2) and also divisible by
