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 10,317,455, 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 | 10,317,455 | |
| -1 | -10,317,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,317,455.
Example:
1 x 10,317,455 = 10,317,455
and
-1 x -10,317,455 = 10,317,455
Notice both answers equal 10,317,455
With that explanation out of the way, let's continue. Next, we take the number 10,317,455 and divide it by 2:
10,317,455 ÷ 2 = 5,158,727.5
If the quotient is a whole number, then 2 and 5,158,727.5 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 | 10,317,455 | |
| -1 | -10,317,455 |
Now, we try dividing 10,317,455 by 3:
10,317,455 ÷ 3 = 3,439,151.6667
If the quotient is a whole number, then 3 and 3,439,151.6667 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 | 10,317,455 | |
| -1 | -10,317,455 |
Let's try dividing by 4:
10,317,455 ÷ 4 = 2,579,363.75
If the quotient is a whole number, then 4 and 2,579,363.75 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 | 10,317,455 | |
| -1 | 10,317,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 73 | 115 | 365 | 1,229 | 1,679 | 6,145 | 8,395 | 28,267 | 89,717 | 141,335 | 448,585 | 2,063,491 | 10,317,455 |
| -1 | -5 | -23 | -73 | -115 | -365 | -1,229 | -1,679 | -6,145 | -8,395 | -28,267 | -89,717 | -141,335 | -448,585 | -2,063,491 | -10,317,455 |
