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 13,068,899, 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 | 13,068,899 | |
| -1 | -13,068,899 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,068,899.
Example:
1 x 13,068,899 = 13,068,899
and
-1 x -13,068,899 = 13,068,899
Notice both answers equal 13,068,899
With that explanation out of the way, let's continue. Next, we take the number 13,068,899 and divide it by 2:
13,068,899 ÷ 2 = 6,534,449.5
If the quotient is a whole number, then 2 and 6,534,449.5 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 | 13,068,899 | |
| -1 | -13,068,899 |
Now, we try dividing 13,068,899 by 3:
13,068,899 ÷ 3 = 4,356,299.6667
If the quotient is a whole number, then 3 and 4,356,299.6667 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 | 13,068,899 | |
| -1 | -13,068,899 |
Let's try dividing by 4:
13,068,899 ÷ 4 = 3,267,224.75
If the quotient is a whole number, then 4 and 3,267,224.75 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 | 13,068,899 | |
| -1 | 13,068,899 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 71 | 151 | 1,219 | 1,633 | 3,473 | 3,763 | 8,003 | 10,721 | 86,549 | 184,069 | 246,583 | 568,213 | 13,068,899 |
| -1 | -23 | -53 | -71 | -151 | -1,219 | -1,633 | -3,473 | -3,763 | -8,003 | -10,721 | -86,549 | -184,069 | -246,583 | -568,213 | -13,068,899 |
