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 7,382,713, 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 | 7,382,713 | |
| -1 | -7,382,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,382,713.
Example:
1 x 7,382,713 = 7,382,713
and
-1 x -7,382,713 = 7,382,713
Notice both answers equal 7,382,713
With that explanation out of the way, let's continue. Next, we take the number 7,382,713 and divide it by 2:
7,382,713 ÷ 2 = 3,691,356.5
If the quotient is a whole number, then 2 and 3,691,356.5 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 | 7,382,713 | |
| -1 | -7,382,713 |
Now, we try dividing 7,382,713 by 3:
7,382,713 ÷ 3 = 2,460,904.3333
If the quotient is a whole number, then 3 and 2,460,904.3333 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 | 7,382,713 | |
| -1 | -7,382,713 |
Let's try dividing by 4:
7,382,713 ÷ 4 = 1,845,678.25
If the quotient is a whole number, then 4 and 1,845,678.25 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 | 7,382,713 | |
| -1 | 7,382,713 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 47 | 281 | 559 | 611 | 2,021 | 3,653 | 12,083 | 13,207 | 26,273 | 157,079 | 171,691 | 567,901 | 7,382,713 |
| -1 | -13 | -43 | -47 | -281 | -559 | -611 | -2,021 | -3,653 | -12,083 | -13,207 | -26,273 | -157,079 | -171,691 | -567,901 | -7,382,713 |
