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 28,305,233, 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 | 28,305,233 | |
| -1 | -28,305,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,305,233.
Example:
1 x 28,305,233 = 28,305,233
and
-1 x -28,305,233 = 28,305,233
Notice both answers equal 28,305,233
With that explanation out of the way, let's continue. Next, we take the number 28,305,233 and divide it by 2:
28,305,233 ÷ 2 = 14,152,616.5
If the quotient is a whole number, then 2 and 14,152,616.5 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 | 28,305,233 | |
| -1 | -28,305,233 |
Now, we try dividing 28,305,233 by 3:
28,305,233 ÷ 3 = 9,435,077.6667
If the quotient is a whole number, then 3 and 9,435,077.6667 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 | 28,305,233 | |
| -1 | -28,305,233 |
Let's try dividing by 4:
28,305,233 ÷ 4 = 7,076,308.25
If the quotient is a whole number, then 4 and 7,076,308.25 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 | 28,305,233 | |
| -1 | 28,305,233 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 53 | 517 | 583 | 1,033 | 2,491 | 11,363 | 27,401 | 48,551 | 54,749 | 534,061 | 602,239 | 2,573,203 | 28,305,233 |
| -1 | -11 | -47 | -53 | -517 | -583 | -1,033 | -2,491 | -11,363 | -27,401 | -48,551 | -54,749 | -534,061 | -602,239 | -2,573,203 | -28,305,233 |
