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 43,516,187, 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 | 43,516,187 | |
| -1 | -43,516,187 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,516,187.
Example:
1 x 43,516,187 = 43,516,187
and
-1 x -43,516,187 = 43,516,187
Notice both answers equal 43,516,187
With that explanation out of the way, let's continue. Next, we take the number 43,516,187 and divide it by 2:
43,516,187 ÷ 2 = 21,758,093.5
If the quotient is a whole number, then 2 and 21,758,093.5 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 | 43,516,187 | |
| -1 | -43,516,187 |
Now, we try dividing 43,516,187 by 3:
43,516,187 ÷ 3 = 14,505,395.6667
If the quotient is a whole number, then 3 and 14,505,395.6667 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 | 43,516,187 | |
| -1 | -43,516,187 |
Let's try dividing by 4:
43,516,187 ÷ 4 = 10,879,046.75
If the quotient is a whole number, then 4 and 10,879,046.75 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 | 43,516,187 | |
| -1 | 43,516,187 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 113 | 143 | 1,243 | 1,469 | 2,693 | 16,159 | 29,623 | 35,009 | 304,309 | 385,099 | 3,347,399 | 3,956,017 | 43,516,187 |
| -1 | -11 | -13 | -113 | -143 | -1,243 | -1,469 | -2,693 | -16,159 | -29,623 | -35,009 | -304,309 | -385,099 | -3,347,399 | -3,956,017 | -43,516,187 |
