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 13,113,059, 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 | 13,113,059 | |
| -1 | -13,113,059 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,113,059.
Example:
1 x 13,113,059 = 13,113,059
and
-1 x -13,113,059 = 13,113,059
Notice both answers equal 13,113,059
With that explanation out of the way, let's continue. Next, we take the number 13,113,059 and divide it by 2:
13,113,059 ÷ 2 = 6,556,529.5
If the quotient is a whole number, then 2 and 6,556,529.5 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 | 13,113,059 | |
| -1 | -13,113,059 |
Now, we try dividing 13,113,059 by 3:
13,113,059 ÷ 3 = 4,371,019.6667
If the quotient is a whole number, then 3 and 4,371,019.6667 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 | 13,113,059 | |
| -1 | -13,113,059 |
Let's try dividing by 4:
13,113,059 ÷ 4 = 3,278,264.75
If the quotient is a whole number, then 4 and 3,278,264.75 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 | 13,113,059 | |
| -1 | 13,113,059 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 37 | 437 | 703 | 811 | 851 | 15,409 | 16,169 | 18,653 | 30,007 | 354,407 | 570,133 | 690,161 | 13,113,059 |
| -1 | -19 | -23 | -37 | -437 | -703 | -811 | -851 | -15,409 | -16,169 | -18,653 | -30,007 | -354,407 | -570,133 | -690,161 | -13,113,059 |
