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 7,471,373, 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 | 7,471,373 | |
| -1 | -7,471,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,471,373.
Example:
1 x 7,471,373 = 7,471,373
and
-1 x -7,471,373 = 7,471,373
Notice both answers equal 7,471,373
With that explanation out of the way, let's continue. Next, we take the number 7,471,373 and divide it by 2:
7,471,373 ÷ 2 = 3,735,686.5
If the quotient is a whole number, then 2 and 3,735,686.5 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 | 7,471,373 | |
| -1 | -7,471,373 |
Now, we try dividing 7,471,373 by 3:
7,471,373 ÷ 3 = 2,490,457.6667
If the quotient is a whole number, then 3 and 2,490,457.6667 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 | 7,471,373 | |
| -1 | -7,471,373 |
Let's try dividing by 4:
7,471,373 ÷ 4 = 1,867,843.25
If the quotient is a whole number, then 4 and 1,867,843.25 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 | 7,471,373 | |
| -1 | 7,471,373 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 49 | 91 | 259 | 317 | 481 | 637 | 1,813 | 2,219 | 3,367 | 4,121 | 11,729 | 15,533 | 23,569 | 28,847 | 82,103 | 152,477 | 201,929 | 574,721 | 1,067,339 | 7,471,373 |
| -1 | -7 | -13 | -37 | -49 | -91 | -259 | -317 | -481 | -637 | -1,813 | -2,219 | -3,367 | -4,121 | -11,729 | -15,533 | -23,569 | -28,847 | -82,103 | -152,477 | -201,929 | -574,721 | -1,067,339 | -7,471,373 |
