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 10,404,251, 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 | 10,404,251 | |
| -1 | -10,404,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,404,251.
Example:
1 x 10,404,251 = 10,404,251
and
-1 x -10,404,251 = 10,404,251
Notice both answers equal 10,404,251
With that explanation out of the way, let's continue. Next, we take the number 10,404,251 and divide it by 2:
10,404,251 ÷ 2 = 5,202,125.5
If the quotient is a whole number, then 2 and 5,202,125.5 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 | 10,404,251 | |
| -1 | -10,404,251 |
Now, we try dividing 10,404,251 by 3:
10,404,251 ÷ 3 = 3,468,083.6667
If the quotient is a whole number, then 3 and 3,468,083.6667 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 | 10,404,251 | |
| -1 | -10,404,251 |
Let's try dividing by 4:
10,404,251 ÷ 4 = 2,601,062.75
If the quotient is a whole number, then 4 and 2,601,062.75 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 | 10,404,251 | |
| -1 | 10,404,251 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 31 | 143 | 341 | 403 | 2,347 | 4,433 | 25,817 | 30,511 | 72,757 | 335,621 | 800,327 | 945,841 | 10,404,251 |
| -1 | -11 | -13 | -31 | -143 | -341 | -403 | -2,347 | -4,433 | -25,817 | -30,511 | -72,757 | -335,621 | -800,327 | -945,841 | -10,404,251 |
