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 7,244,705, 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 | 7,244,705 | |
| -1 | -7,244,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,244,705.
Example:
1 x 7,244,705 = 7,244,705
and
-1 x -7,244,705 = 7,244,705
Notice both answers equal 7,244,705
With that explanation out of the way, let's continue. Next, we take the number 7,244,705 and divide it by 2:
7,244,705 ÷ 2 = 3,622,352.5
If the quotient is a whole number, then 2 and 3,622,352.5 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 | 7,244,705 | |
| -1 | -7,244,705 |
Now, we try dividing 7,244,705 by 3:
7,244,705 ÷ 3 = 2,414,901.6667
If the quotient is a whole number, then 3 and 2,414,901.6667 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 | 7,244,705 | |
| -1 | -7,244,705 |
Let's try dividing by 4:
7,244,705 ÷ 4 = 1,811,176.25
If the quotient is a whole number, then 4 and 1,811,176.25 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 | 7,244,705 | |
| -1 | 7,244,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 227 | 491 | 1,135 | 2,455 | 2,951 | 6,383 | 14,755 | 31,915 | 111,457 | 557,285 | 1,448,941 | 7,244,705 |
| -1 | -5 | -13 | -65 | -227 | -491 | -1,135 | -2,455 | -2,951 | -6,383 | -14,755 | -31,915 | -111,457 | -557,285 | -1,448,941 | -7,244,705 |
