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 13,073,599, 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 | 13,073,599 | |
| -1 | -13,073,599 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,073,599.
Example:
1 x 13,073,599 = 13,073,599
and
-1 x -13,073,599 = 13,073,599
Notice both answers equal 13,073,599
With that explanation out of the way, let's continue. Next, we take the number 13,073,599 and divide it by 2:
13,073,599 ÷ 2 = 6,536,799.5
If the quotient is a whole number, then 2 and 6,536,799.5 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 | 13,073,599 | |
| -1 | -13,073,599 |
Now, we try dividing 13,073,599 by 3:
13,073,599 ÷ 3 = 4,357,866.3333
If the quotient is a whole number, then 3 and 4,357,866.3333 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 | 13,073,599 | |
| -1 | -13,073,599 |
Let's try dividing by 4:
13,073,599 ÷ 4 = 3,268,399.75
If the quotient is a whole number, then 4 and 3,268,399.75 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 | 13,073,599 | |
| -1 | 13,073,599 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 5,477 | 38,339 | 60,247 | 169,787 | 421,729 | 1,188,509 | 1,867,657 | 13,073,599 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -5,477 | -38,339 | -60,247 | -169,787 | -421,729 | -1,188,509 | -1,867,657 | -13,073,599 |
