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 7,114,525, 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 | 7,114,525 | |
| -1 | -7,114,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,114,525.
Example:
1 x 7,114,525 = 7,114,525
and
-1 x -7,114,525 = 7,114,525
Notice both answers equal 7,114,525
With that explanation out of the way, let's continue. Next, we take the number 7,114,525 and divide it by 2:
7,114,525 ÷ 2 = 3,557,262.5
If the quotient is a whole number, then 2 and 3,557,262.5 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 | 7,114,525 | |
| -1 | -7,114,525 |
Now, we try dividing 7,114,525 by 3:
7,114,525 ÷ 3 = 2,371,508.3333
If the quotient is a whole number, then 3 and 2,371,508.3333 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 | 7,114,525 | |
| -1 | -7,114,525 |
Let's try dividing by 4:
7,114,525 ÷ 4 = 1,778,631.25
If the quotient is a whole number, then 4 and 1,778,631.25 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 | 7,114,525 | |
| -1 | 7,114,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 41 | 55 | 205 | 275 | 451 | 631 | 1,025 | 2,255 | 3,155 | 6,941 | 11,275 | 15,775 | 25,871 | 34,705 | 129,355 | 173,525 | 284,581 | 646,775 | 1,422,905 | 7,114,525 |
| -1 | -5 | -11 | -25 | -41 | -55 | -205 | -275 | -451 | -631 | -1,025 | -2,255 | -3,155 | -6,941 | -11,275 | -15,775 | -25,871 | -34,705 | -129,355 | -173,525 | -284,581 | -646,775 | -1,422,905 | -7,114,525 |
