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 7,471,105, 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 | 7,471,105 | |
| -1 | -7,471,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,471,105.
Example:
1 x 7,471,105 = 7,471,105
and
-1 x -7,471,105 = 7,471,105
Notice both answers equal 7,471,105
With that explanation out of the way, let's continue. Next, we take the number 7,471,105 and divide it by 2:
7,471,105 ÷ 2 = 3,735,552.5
If the quotient is a whole number, then 2 and 3,735,552.5 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 | 7,471,105 | |
| -1 | -7,471,105 |
Now, we try dividing 7,471,105 by 3:
7,471,105 ÷ 3 = 2,490,368.3333
If the quotient is a whole number, then 3 and 2,490,368.3333 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 | 7,471,105 | |
| -1 | -7,471,105 |
Let's try dividing by 4:
7,471,105 ÷ 4 = 1,867,776.25
If the quotient is a whole number, then 4 and 1,867,776.25 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 | 7,471,105 | |
| -1 | 7,471,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 103 | 163 | 445 | 515 | 815 | 9,167 | 14,507 | 16,789 | 45,835 | 72,535 | 83,945 | 1,494,221 | 7,471,105 |
| -1 | -5 | -89 | -103 | -163 | -445 | -515 | -815 | -9,167 | -14,507 | -16,789 | -45,835 | -72,535 | -83,945 | -1,494,221 | -7,471,105 |
