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 43,889,155, 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 | 43,889,155 | |
| -1 | -43,889,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,889,155.
Example:
1 x 43,889,155 = 43,889,155
and
-1 x -43,889,155 = 43,889,155
Notice both answers equal 43,889,155
With that explanation out of the way, let's continue. Next, we take the number 43,889,155 and divide it by 2:
43,889,155 ÷ 2 = 21,944,577.5
If the quotient is a whole number, then 2 and 21,944,577.5 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 | 43,889,155 | |
| -1 | -43,889,155 |
Now, we try dividing 43,889,155 by 3:
43,889,155 ÷ 3 = 14,629,718.3333
If the quotient is a whole number, then 3 and 14,629,718.3333 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 | 43,889,155 | |
| -1 | -43,889,155 |
Let's try dividing by 4:
43,889,155 ÷ 4 = 10,972,288.75
If the quotient is a whole number, then 4 and 10,972,288.75 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 | 43,889,155 | |
| -1 | 43,889,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 83 | 85 | 415 | 1,411 | 6,221 | 7,055 | 31,105 | 105,757 | 516,343 | 528,785 | 2,581,715 | 8,777,831 | 43,889,155 |
| -1 | -5 | -17 | -83 | -85 | -415 | -1,411 | -6,221 | -7,055 | -31,105 | -105,757 | -516,343 | -528,785 | -2,581,715 | -8,777,831 | -43,889,155 |
