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 13,794,431, 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 | 13,794,431 | |
| -1 | -13,794,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,794,431.
Example:
1 x 13,794,431 = 13,794,431
and
-1 x -13,794,431 = 13,794,431
Notice both answers equal 13,794,431
With that explanation out of the way, let's continue. Next, we take the number 13,794,431 and divide it by 2:
13,794,431 ÷ 2 = 6,897,215.5
If the quotient is a whole number, then 2 and 6,897,215.5 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 | 13,794,431 | |
| -1 | -13,794,431 |
Now, we try dividing 13,794,431 by 3:
13,794,431 ÷ 3 = 4,598,143.6667
If the quotient is a whole number, then 3 and 4,598,143.6667 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 | 13,794,431 | |
| -1 | -13,794,431 |
Let's try dividing by 4:
13,794,431 ÷ 4 = 3,448,607.75
If the quotient is a whole number, then 4 and 3,448,607.75 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 | 13,794,431 | |
| -1 | 13,794,431 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 131 | 307 | 343 | 917 | 2,149 | 6,419 | 15,043 | 40,217 | 44,933 | 105,301 | 281,519 | 1,970,633 | 13,794,431 |
| -1 | -7 | -49 | -131 | -307 | -343 | -917 | -2,149 | -6,419 | -15,043 | -40,217 | -44,933 | -105,301 | -281,519 | -1,970,633 | -13,794,431 |
