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 10,216,453, 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 | 10,216,453 | |
| -1 | -10,216,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,216,453.
Example:
1 x 10,216,453 = 10,216,453
and
-1 x -10,216,453 = 10,216,453
Notice both answers equal 10,216,453
With that explanation out of the way, let's continue. Next, we take the number 10,216,453 and divide it by 2:
10,216,453 ÷ 2 = 5,108,226.5
If the quotient is a whole number, then 2 and 5,108,226.5 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 | 10,216,453 | |
| -1 | -10,216,453 |
Now, we try dividing 10,216,453 by 3:
10,216,453 ÷ 3 = 3,405,484.3333
If the quotient is a whole number, then 3 and 3,405,484.3333 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 | 10,216,453 | |
| -1 | -10,216,453 |
Let's try dividing by 4:
10,216,453 ÷ 4 = 2,554,113.25
If the quotient is a whole number, then 4 and 2,554,113.25 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 | 10,216,453 | |
| -1 | 10,216,453 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 101 | 251 | 403 | 1,313 | 3,131 | 3,263 | 7,781 | 25,351 | 40,703 | 101,153 | 329,563 | 785,881 | 10,216,453 |
| -1 | -13 | -31 | -101 | -251 | -403 | -1,313 | -3,131 | -3,263 | -7,781 | -25,351 | -40,703 | -101,153 | -329,563 | -785,881 | -10,216,453 |
