No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.
1, 2 and 7.
A compatible number is a number that is easy to add when you add it together.
No, 92 is not a multiple of 3. A quick way to check if a number is a multiple of 3 is: add up the digits of the number you are checking; if this sum equals 3 or a multiple of 3, then the number is a multiple of 3. So in this case, 92 --> 9+2=11, which is not a multiple of 3. If you have to you can add again, so for 11 --> 1+1=2, which is not a multiple of 3. You can always repetitively add until you get to a single digit answer: if it's 3,6 or 9 then it's a multiple of 3. Also if your sum is 9 or a multiple of 9, then the original number is a multiple of 9. To check for 6, if a number is a multiple of 3, and also a multiple of 2 (an even number), then the number is a multiple of 6.
7 & 11 added together total 18.

Only if they are odd.
1, 2 and 7.
Add
You add each number together, and then divide it by the total amount of sales. For example, $30.00, $15.00, and $70.00. You add the three together, and then divide the sum by three.
2084 is a multiple of 4 . Add together 521 '4's and you will have 2084.
Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.
The number you're looking for is 4. It's an even number, and when you add 5 to it, the result is 9, which is a multiple of 3.
To test if a number is a multiple of 3, add the digits together and if the result is a multiple of 3, the original number is also a multiple of 3: 11154: 1 + 1 + 1 + 5 + 4 = 12 = 3 x 4, a multiple of 3, thus 11154 is a multiple of 3. (11154 = 3 x 3718)
add them all together and then divide the answer by the number of numbers.
A compatible number is a number that is easy to add when you add it together.
It is not possible to add together 5 odd numbers to make an even number.
