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 7,105,183, 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 | 7,105,183 | |
| -1 | -7,105,183 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,105,183.
Example:
1 x 7,105,183 = 7,105,183
and
-1 x -7,105,183 = 7,105,183
Notice both answers equal 7,105,183
With that explanation out of the way, let's continue. Next, we take the number 7,105,183 and divide it by 2:
7,105,183 ÷ 2 = 3,552,591.5
If the quotient is a whole number, then 2 and 3,552,591.5 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 | 7,105,183 | |
| -1 | -7,105,183 |
Now, we try dividing 7,105,183 by 3:
7,105,183 ÷ 3 = 2,368,394.3333
If the quotient is a whole number, then 3 and 2,368,394.3333 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 | 7,105,183 | |
| -1 | -7,105,183 |
Let's try dividing by 4:
7,105,183 ÷ 4 = 1,776,295.75
If the quotient is a whole number, then 4 and 1,776,295.75 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 | 7,105,183 | |
| -1 | 7,105,183 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 71 | 229 | 437 | 1,349 | 1,633 | 4,351 | 5,267 | 16,259 | 31,027 | 100,073 | 308,921 | 373,957 | 7,105,183 |
| -1 | -19 | -23 | -71 | -229 | -437 | -1,349 | -1,633 | -4,351 | -5,267 | -16,259 | -31,027 | -100,073 | -308,921 | -373,957 | -7,105,183 |
