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 7,383,905, 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 | 7,383,905 | |
| -1 | -7,383,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,383,905.
Example:
1 x 7,383,905 = 7,383,905
and
-1 x -7,383,905 = 7,383,905
Notice both answers equal 7,383,905
With that explanation out of the way, let's continue. Next, we take the number 7,383,905 and divide it by 2:
7,383,905 ÷ 2 = 3,691,952.5
If the quotient is a whole number, then 2 and 3,691,952.5 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 | 7,383,905 | |
| -1 | -7,383,905 |
Now, we try dividing 7,383,905 by 3:
7,383,905 ÷ 3 = 2,461,301.6667
If the quotient is a whole number, then 3 and 2,461,301.6667 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 | 7,383,905 | |
| -1 | -7,383,905 |
Let's try dividing by 4:
7,383,905 ÷ 4 = 1,845,976.25
If the quotient is a whole number, then 4 and 1,845,976.25 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 | 7,383,905 | |
| -1 | 7,383,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 167 | 185 | 239 | 835 | 1,195 | 6,179 | 8,843 | 30,895 | 39,913 | 44,215 | 199,565 | 1,476,781 | 7,383,905 |
| -1 | -5 | -37 | -167 | -185 | -239 | -835 | -1,195 | -6,179 | -8,843 | -30,895 | -39,913 | -44,215 | -199,565 | -1,476,781 | -7,383,905 |
