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 10,454,405, 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 | 10,454,405 | |
| -1 | -10,454,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,454,405.
Example:
1 x 10,454,405 = 10,454,405
and
-1 x -10,454,405 = 10,454,405
Notice both answers equal 10,454,405
With that explanation out of the way, let's continue. Next, we take the number 10,454,405 and divide it by 2:
10,454,405 ÷ 2 = 5,227,202.5
If the quotient is a whole number, then 2 and 5,227,202.5 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 | 10,454,405 | |
| -1 | -10,454,405 |
Now, we try dividing 10,454,405 by 3:
10,454,405 ÷ 3 = 3,484,801.6667
If the quotient is a whole number, then 3 and 3,484,801.6667 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 | 10,454,405 | |
| -1 | -10,454,405 |
Let's try dividing by 4:
10,454,405 ÷ 4 = 2,613,601.25
If the quotient is a whole number, then 4 and 2,613,601.25 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 | 10,454,405 | |
| -1 | 10,454,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 9,461 | 47,305 | 122,993 | 160,837 | 614,965 | 804,185 | 2,090,881 | 10,454,405 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -9,461 | -47,305 | -122,993 | -160,837 | -614,965 | -804,185 | -2,090,881 | -10,454,405 |
