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 13,073,159, 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 | 13,073,159 | |
| -1 | -13,073,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,073,159.
Example:
1 x 13,073,159 = 13,073,159
and
-1 x -13,073,159 = 13,073,159
Notice both answers equal 13,073,159
With that explanation out of the way, let's continue. Next, we take the number 13,073,159 and divide it by 2:
13,073,159 ÷ 2 = 6,536,579.5
If the quotient is a whole number, then 2 and 6,536,579.5 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 | 13,073,159 | |
| -1 | -13,073,159 |
Now, we try dividing 13,073,159 by 3:
13,073,159 ÷ 3 = 4,357,719.6667
If the quotient is a whole number, then 3 and 4,357,719.6667 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 | 13,073,159 | |
| -1 | -13,073,159 |
Let's try dividing by 4:
13,073,159 ÷ 4 = 3,268,289.75
If the quotient is a whole number, then 4 and 3,268,289.75 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 | 13,073,159 | |
| -1 | 13,073,159 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 71 | 209 | 781 | 881 | 1,349 | 9,691 | 14,839 | 16,739 | 62,551 | 184,129 | 688,061 | 1,188,469 | 13,073,159 |
| -1 | -11 | -19 | -71 | -209 | -781 | -881 | -1,349 | -9,691 | -14,839 | -16,739 | -62,551 | -184,129 | -688,061 | -1,188,469 | -13,073,159 |
