Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 28,933,331, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 28,933,331 | |
| -1 | -28,933,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,933,331.
Example:
1 x 28,933,331 = 28,933,331
and
-1 x -28,933,331 = 28,933,331
Notice both answers equal 28,933,331
With that explanation out of the way, let's continue. Next, we take the number 28,933,331 and divide it by 2:
28,933,331 ÷ 2 = 14,466,665.5
If the quotient is a whole number, then 2 and 14,466,665.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 28,933,331 | |
| -1 | -28,933,331 |
Now, we try dividing 28,933,331 by 3:
28,933,331 ÷ 3 = 9,644,443.6667
If the quotient is a whole number, then 3 and 9,644,443.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 28,933,331 | |
| -1 | -28,933,331 |
Let's try dividing by 4:
28,933,331 ÷ 4 = 7,233,332.75
If the quotient is a whole number, then 4 and 7,233,332.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 28,933,331 | |
| -1 | 28,933,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 73 | 287 | 511 | 1,381 | 2,993 | 9,667 | 20,951 | 56,621 | 100,813 | 396,347 | 705,691 | 4,133,333 | 28,933,331 |
| -1 | -7 | -41 | -73 | -287 | -511 | -1,381 | -2,993 | -9,667 | -20,951 | -56,621 | -100,813 | -396,347 | -705,691 | -4,133,333 | -28,933,331 |
