The Answer :)

- If the number is divisible by 2

and

- If the number is divisible by 3

To find out if the number is divisible by 2 you look at the last digit of the number and see if it's an even number...

ex: 420 you look at the 0 and 0 is a even number so 420 is divisible by 2.

To find out if a number is divisible by 3 you add all the digits together and then see if the sum is divisible by 3...

ex: 420 you add 4+2+0= 6 . and 6 is divisible by 3 so the number 420 is divisible by 3.

yeah!

the number will also be divisible by 3 and 2

The way to know if a number is divisible by 3 is if its digit sum adds up to a number that is divisible by 3 (3, 6 or 9). The way to know if a number is divisible by 2 is if that number is even. That is, a number is divisible by two if the units are 0, 2, 4, 6 or 8. A number is divisible by 6 if it meets both these rules. In this case, 402 has the digit sum 6, and the units value is 2. Therefore, we can say that 402 is divisible by 6.

If a number is divisible by 2 and 3, it is divisible by 6.

Since 3 is a factor of 6, any number divisible by 6 is also divisible by 3. But since 2 is also a factor of 6, then any number divisible by 6 must also be divisible by 2. This means that any number divisible by 6 is an even number. So if a number is odd and it is divisible by 3, then it is not divisible by 6. For example, 12 is divisible by 3, but since it is even, it is also divisible by 6. But 15 is divisible by 3, and it is odd, so it is not divisible by 6.

There can be no such number. If it is divisible by 5 and 6it must be divisible by 6.

$no = 23; if($no % 6 == 0) { echo "$no is divisible by 6"; }else{ echo "$no is NOT divisible by 6"; }

No odd number can be evenly divisible by 6. Since 6 is divisible by 2, any number that is divisible by 6 will automatically be divisible by 2.

There is no such number. Since 6 is divisible by 3, then any number that is divisible by 6 automatically has to be divisible by 3.

138 is divisible by 6. Any number is divisible by 6 if it is an even number that also is divisible by 3.

These numbers are not evenly divisible by 6: Any number smaller than 6. Any odd number (not divisible by 2). Any number not divisible by 3. If a number is divisible by both 2 and 3, it is divisible by 6.

If this is a T-F question, the answer is false. It is true that if a number is divisible by 6, it also divisible by 3. This is true because 6 is divisible by 3. However, the converse -- If a number is divisible by 3, it is divisible by 6, is false. A counterexample is 15. 15 is divisible by 3, but not by 6. It becomes clearer if you split the question into its two parts. A number is divisible by 6 if it is divisible by 3? False. It must also be divisible by 2. A number is divisible by 6 only if it is divisible by 3? True.

if a number is divisible by 2 and 3 then its divisible by 6

If a number is divisible by 2 and 3, it is divisible by 6.

Quickly check to see whether it's divisible by both 2 and 3. Here's how to do that easily: -- The number is divisible by 2 if it's an even number . . . the last digit is 2, 4, 6, 8, or 0. -- The number is divisible by 3 if the sum of its digits is divisible by 3.

The product of any number and 6 would be divisible by 6.
