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 4,131,113, 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 | 4,131,113 | |
| -1 | -4,131,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,131,113.
Example:
1 x 4,131,113 = 4,131,113
and
-1 x -4,131,113 = 4,131,113
Notice both answers equal 4,131,113
With that explanation out of the way, let's continue. Next, we take the number 4,131,113 and divide it by 2:
4,131,113 ÷ 2 = 2,065,556.5
If the quotient is a whole number, then 2 and 2,065,556.5 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 | 4,131,113 | |
| -1 | -4,131,113 |
Now, we try dividing 4,131,113 by 3:
4,131,113 ÷ 3 = 1,377,037.6667
If the quotient is a whole number, then 3 and 1,377,037.6667 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 | 4,131,113 | |
| -1 | -4,131,113 |
Let's try dividing by 4:
4,131,113 ÷ 4 = 1,032,778.25
If the quotient is a whole number, then 4 and 1,032,778.25 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 | 4,131,113 | |
| -1 | 4,131,113 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 89 | 133 | 349 | 623 | 1,691 | 2,443 | 6,631 | 11,837 | 31,061 | 46,417 | 217,427 | 590,159 | 4,131,113 |
| -1 | -7 | -19 | -89 | -133 | -349 | -623 | -1,691 | -2,443 | -6,631 | -11,837 | -31,061 | -46,417 | -217,427 | -590,159 | -4,131,113 |
