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 4,173,005, 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 | 4,173,005 | |
| -1 | -4,173,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,173,005.
Example:
1 x 4,173,005 = 4,173,005
and
-1 x -4,173,005 = 4,173,005
Notice both answers equal 4,173,005
With that explanation out of the way, let's continue. Next, we take the number 4,173,005 and divide it by 2:
4,173,005 ÷ 2 = 2,086,502.5
If the quotient is a whole number, then 2 and 2,086,502.5 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 | 4,173,005 | |
| -1 | -4,173,005 |
Now, we try dividing 4,173,005 by 3:
4,173,005 ÷ 3 = 1,391,001.6667
If the quotient is a whole number, then 3 and 1,391,001.6667 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 | 4,173,005 | |
| -1 | -4,173,005 |
Let's try dividing by 4:
4,173,005 ÷ 4 = 1,043,251.25
If the quotient is a whole number, then 4 and 1,043,251.25 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 | 4,173,005 | |
| -1 | 4,173,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 131 | 277 | 655 | 1,385 | 3,013 | 6,371 | 15,065 | 31,855 | 36,287 | 181,435 | 834,601 | 4,173,005 |
| -1 | -5 | -23 | -115 | -131 | -277 | -655 | -1,385 | -3,013 | -6,371 | -15,065 | -31,855 | -36,287 | -181,435 | -834,601 | -4,173,005 |
