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 11,601,305, 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 | 11,601,305 | |
| -1 | -11,601,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,601,305.
Example:
1 x 11,601,305 = 11,601,305
and
-1 x -11,601,305 = 11,601,305
Notice both answers equal 11,601,305
With that explanation out of the way, let's continue. Next, we take the number 11,601,305 and divide it by 2:
11,601,305 ÷ 2 = 5,800,652.5
If the quotient is a whole number, then 2 and 5,800,652.5 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 | 11,601,305 | |
| -1 | -11,601,305 |
Now, we try dividing 11,601,305 by 3:
11,601,305 ÷ 3 = 3,867,101.6667
If the quotient is a whole number, then 3 and 3,867,101.6667 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 | 11,601,305 | |
| -1 | -11,601,305 |
Let's try dividing by 4:
11,601,305 ÷ 4 = 2,900,326.25
If the quotient is a whole number, then 4 and 2,900,326.25 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 | 11,601,305 | |
| -1 | 11,601,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 29 | 95 | 145 | 551 | 2,755 | 4,211 | 21,055 | 80,009 | 122,119 | 400,045 | 610,595 | 2,320,261 | 11,601,305 |
| -1 | -5 | -19 | -29 | -95 | -145 | -551 | -2,755 | -4,211 | -21,055 | -80,009 | -122,119 | -400,045 | -610,595 | -2,320,261 | -11,601,305 |
