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 13,164,359, 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 | 13,164,359 | |
| -1 | -13,164,359 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,164,359.
Example:
1 x 13,164,359 = 13,164,359
and
-1 x -13,164,359 = 13,164,359
Notice both answers equal 13,164,359
With that explanation out of the way, let's continue. Next, we take the number 13,164,359 and divide it by 2:
13,164,359 ÷ 2 = 6,582,179.5
If the quotient is a whole number, then 2 and 6,582,179.5 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 | 13,164,359 | |
| -1 | -13,164,359 |
Now, we try dividing 13,164,359 by 3:
13,164,359 ÷ 3 = 4,388,119.6667
If the quotient is a whole number, then 3 and 4,388,119.6667 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 | 13,164,359 | |
| -1 | -13,164,359 |
Let's try dividing by 4:
13,164,359 ÷ 4 = 3,291,089.75
If the quotient is a whole number, then 4 and 3,291,089.75 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 | 13,164,359 | |
| -1 | 13,164,359 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 223 | 239 | 247 | 2,899 | 3,107 | 4,237 | 4,541 | 53,297 | 55,081 | 59,033 | 692,861 | 1,012,643 | 13,164,359 |
| -1 | -13 | -19 | -223 | -239 | -247 | -2,899 | -3,107 | -4,237 | -4,541 | -53,297 | -55,081 | -59,033 | -692,861 | -1,012,643 | -13,164,359 |
