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 11,964,155, 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 | 11,964,155 | |
| -1 | -11,964,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,964,155.
Example:
1 x 11,964,155 = 11,964,155
and
-1 x -11,964,155 = 11,964,155
Notice both answers equal 11,964,155
With that explanation out of the way, let's continue. Next, we take the number 11,964,155 and divide it by 2:
11,964,155 ÷ 2 = 5,982,077.5
If the quotient is a whole number, then 2 and 5,982,077.5 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 | 11,964,155 | |
| -1 | -11,964,155 |
Now, we try dividing 11,964,155 by 3:
11,964,155 ÷ 3 = 3,988,051.6667
If the quotient is a whole number, then 3 and 3,988,051.6667 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 | 11,964,155 | |
| -1 | -11,964,155 |
Let's try dividing by 4:
11,964,155 ÷ 4 = 2,991,038.75
If the quotient is a whole number, then 4 and 2,991,038.75 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 | 11,964,155 | |
| -1 | 11,964,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 2,765 | 4,327 | 21,635 | 30,289 | 151,445 | 341,833 | 1,709,165 | 2,392,831 | 11,964,155 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -2,765 | -4,327 | -21,635 | -30,289 | -151,445 | -341,833 | -1,709,165 | -2,392,831 | -11,964,155 |
