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 43,280,081, 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 | 43,280,081 | |
| -1 | -43,280,081 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,280,081.
Example:
1 x 43,280,081 = 43,280,081
and
-1 x -43,280,081 = 43,280,081
Notice both answers equal 43,280,081
With that explanation out of the way, let's continue. Next, we take the number 43,280,081 and divide it by 2:
43,280,081 ÷ 2 = 21,640,040.5
If the quotient is a whole number, then 2 and 21,640,040.5 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 | 43,280,081 | |
| -1 | -43,280,081 |
Now, we try dividing 43,280,081 by 3:
43,280,081 ÷ 3 = 14,426,693.6667
If the quotient is a whole number, then 3 and 14,426,693.6667 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 | 43,280,081 | |
| -1 | -43,280,081 |
Let's try dividing by 4:
43,280,081 ÷ 4 = 10,820,020.25
If the quotient is a whole number, then 4 and 10,820,020.25 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 | 43,280,081 | |
| -1 | 43,280,081 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 137 | 247 | 1,279 | 1,781 | 2,603 | 16,627 | 24,301 | 33,839 | 175,223 | 315,913 | 2,277,899 | 3,329,237 | 43,280,081 |
| -1 | -13 | -19 | -137 | -247 | -1,279 | -1,781 | -2,603 | -16,627 | -24,301 | -33,839 | -175,223 | -315,913 | -2,277,899 | -3,329,237 | -43,280,081 |
