Question

using divisibility test determine which of the following numbers are divisible by 2,3and6 a) 128​

Answer 1

Answer:

It is only divisible by 2.

Step-by-step explanation:

2 - If a number is divisible by 2 to the last digit of the number should be even.

3 - if a number is divisible by 3 the sum of a digit should be divisible by 3

6 - if a number is divisible by 6 it also should be divisible by 2 and 3.

here you can see 128 is divisible by 2 as its last digit is even but the sum of the three digits is 11 which is not divisible by 3 so the number is also not divisible by 3. the number is not divisible by 6 as it is divisible by 2 but not by 3.
