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 11,551,265, 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 | 11,551,265 | |
| -1 | -11,551,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,551,265.
Example:
1 x 11,551,265 = 11,551,265
and
-1 x -11,551,265 = 11,551,265
Notice both answers equal 11,551,265
With that explanation out of the way, let's continue. Next, we take the number 11,551,265 and divide it by 2:
11,551,265 ÷ 2 = 5,775,632.5
If the quotient is a whole number, then 2 and 5,775,632.5 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 | 11,551,265 | |
| -1 | -11,551,265 |
Now, we try dividing 11,551,265 by 3:
11,551,265 ÷ 3 = 3,850,421.6667
If the quotient is a whole number, then 3 and 3,850,421.6667 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 | 11,551,265 | |
| -1 | -11,551,265 |
Let's try dividing by 4:
11,551,265 ÷ 4 = 2,887,816.25
If the quotient is a whole number, then 4 and 2,887,816.25 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 | 11,551,265 | |
| -1 | 11,551,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 121 | 305 | 313 | 605 | 671 | 1,565 | 3,355 | 3,443 | 7,381 | 17,215 | 19,093 | 36,905 | 37,873 | 95,465 | 189,365 | 210,023 | 1,050,115 | 2,310,253 | 11,551,265 |
| -1 | -5 | -11 | -55 | -61 | -121 | -305 | -313 | -605 | -671 | -1,565 | -3,355 | -3,443 | -7,381 | -17,215 | -19,093 | -36,905 | -37,873 | -95,465 | -189,365 | -210,023 | -1,050,115 | -2,310,253 | -11,551,265 |
