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 12,164,401, 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 | 12,164,401 | |
| -1 | -12,164,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,164,401.
Example:
1 x 12,164,401 = 12,164,401
and
-1 x -12,164,401 = 12,164,401
Notice both answers equal 12,164,401
With that explanation out of the way, let's continue. Next, we take the number 12,164,401 and divide it by 2:
12,164,401 ÷ 2 = 6,082,200.5
If the quotient is a whole number, then 2 and 6,082,200.5 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 | 12,164,401 | |
| -1 | -12,164,401 |
Now, we try dividing 12,164,401 by 3:
12,164,401 ÷ 3 = 4,054,800.3333
If the quotient is a whole number, then 3 and 4,054,800.3333 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 | 12,164,401 | |
| -1 | -12,164,401 |
Let's try dividing by 4:
12,164,401 ÷ 4 = 3,041,100.25
If the quotient is a whole number, then 4 and 3,041,100.25 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 | 12,164,401 | |
| -1 | 12,164,401 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 53 | 391 | 587 | 901 | 1,219 | 9,979 | 13,501 | 20,723 | 31,111 | 229,517 | 528,887 | 715,553 | 12,164,401 |
| -1 | -17 | -23 | -53 | -391 | -587 | -901 | -1,219 | -9,979 | -13,501 | -20,723 | -31,111 | -229,517 | -528,887 | -715,553 | -12,164,401 |
