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 10,251,335, 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 | 10,251,335 | |
| -1 | -10,251,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,251,335.
Example:
1 x 10,251,335 = 10,251,335
and
-1 x -10,251,335 = 10,251,335
Notice both answers equal 10,251,335
With that explanation out of the way, let's continue. Next, we take the number 10,251,335 and divide it by 2:
10,251,335 ÷ 2 = 5,125,667.5
If the quotient is a whole number, then 2 and 5,125,667.5 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 | 10,251,335 | |
| -1 | -10,251,335 |
Now, we try dividing 10,251,335 by 3:
10,251,335 ÷ 3 = 3,417,111.6667
If the quotient is a whole number, then 3 and 3,417,111.6667 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 | 10,251,335 | |
| -1 | -10,251,335 |
Let's try dividing by 4:
10,251,335 ÷ 4 = 2,562,833.75
If the quotient is a whole number, then 4 and 2,562,833.75 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 | 10,251,335 | |
| -1 | 10,251,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 71 | 335 | 355 | 431 | 2,155 | 4,757 | 23,785 | 28,877 | 30,601 | 144,385 | 153,005 | 2,050,267 | 10,251,335 |
| -1 | -5 | -67 | -71 | -335 | -355 | -431 | -2,155 | -4,757 | -23,785 | -28,877 | -30,601 | -144,385 | -153,005 | -2,050,267 | -10,251,335 |
