Answer» Divisibility rule for 6: The prime factor of 6 are 2 and 3 for a number to be divisible by 6, it must ALSO be divisible by 2 and 3. Therefore, we need to check if a number is EVEN and then check if the sum of the digits is divisible by 3. All number are even so all are divisible by 2. For 3, 23562 = 2 + 3 + 5 + 6 + 2 = 18 (Divisible by 3) 43742 = 4 + 3 + 7 + 4 + 2 = 20 (Not divisible by 3) 53422 = 5 + 3 + 4 + 2 + 2 = 16 (Not divisible by 3) 44444 = 4 + 4 + 4 + 4 + 4 = 20 (Not divisible by 3) So, option 1 is ANSWER. |
