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 7,025,369, 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 | 7,025,369 | |
| -1 | -7,025,369 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,025,369.
Example:
1 x 7,025,369 = 7,025,369
and
-1 x -7,025,369 = 7,025,369
Notice both answers equal 7,025,369
With that explanation out of the way, let's continue. Next, we take the number 7,025,369 and divide it by 2:
7,025,369 ÷ 2 = 3,512,684.5
If the quotient is a whole number, then 2 and 3,512,684.5 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 | 7,025,369 | |
| -1 | -7,025,369 |
Now, we try dividing 7,025,369 by 3:
7,025,369 ÷ 3 = 2,341,789.6667
If the quotient is a whole number, then 3 and 2,341,789.6667 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 | 7,025,369 | |
| -1 | -7,025,369 |
Let's try dividing by 4:
7,025,369 ÷ 4 = 1,756,342.25
If the quotient is a whole number, then 4 and 1,756,342.25 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 | 7,025,369 | |
| -1 | 7,025,369 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 83 | 221 | 383 | 1,079 | 1,411 | 4,979 | 6,511 | 18,343 | 31,789 | 84,643 | 413,257 | 540,413 | 7,025,369 |
| -1 | -13 | -17 | -83 | -221 | -383 | -1,079 | -1,411 | -4,979 | -6,511 | -18,343 | -31,789 | -84,643 | -413,257 | -540,413 | -7,025,369 |
