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 11,358,431, 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 | 11,358,431 | |
| -1 | -11,358,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,358,431.
Example:
1 x 11,358,431 = 11,358,431
and
-1 x -11,358,431 = 11,358,431
Notice both answers equal 11,358,431
With that explanation out of the way, let's continue. Next, we take the number 11,358,431 and divide it by 2:
11,358,431 ÷ 2 = 5,679,215.5
If the quotient is a whole number, then 2 and 5,679,215.5 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 | 11,358,431 | |
| -1 | -11,358,431 |
Now, we try dividing 11,358,431 by 3:
11,358,431 ÷ 3 = 3,786,143.6667
If the quotient is a whole number, then 3 and 3,786,143.6667 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 | 11,358,431 | |
| -1 | -11,358,431 |
Let's try dividing by 4:
11,358,431 ÷ 4 = 2,839,607.75
If the quotient is a whole number, then 4 and 2,839,607.75 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 | 11,358,431 | |
| -1 | 11,358,431 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 31 | 119 | 217 | 527 | 3,079 | 3,689 | 21,553 | 52,343 | 95,449 | 366,401 | 668,143 | 1,622,633 | 11,358,431 |
| -1 | -7 | -17 | -31 | -119 | -217 | -527 | -3,079 | -3,689 | -21,553 | -52,343 | -95,449 | -366,401 | -668,143 | -1,622,633 | -11,358,431 |
