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 8,175,005, 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 | 8,175,005 | |
| -1 | -8,175,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,175,005.
Example:
1 x 8,175,005 = 8,175,005
and
-1 x -8,175,005 = 8,175,005
Notice both answers equal 8,175,005
With that explanation out of the way, let's continue. Next, we take the number 8,175,005 and divide it by 2:
8,175,005 ÷ 2 = 4,087,502.5
If the quotient is a whole number, then 2 and 4,087,502.5 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 | 8,175,005 | |
| -1 | -8,175,005 |
Now, we try dividing 8,175,005 by 3:
8,175,005 ÷ 3 = 2,725,001.6667
If the quotient is a whole number, then 3 and 2,725,001.6667 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 | 8,175,005 | |
| -1 | -8,175,005 |
Let's try dividing by 4:
8,175,005 ÷ 4 = 2,043,751.25
If the quotient is a whole number, then 4 and 2,043,751.25 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 | 8,175,005 | |
| -1 | 8,175,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 67 | 115 | 335 | 1,061 | 1,541 | 5,305 | 7,705 | 24,403 | 71,087 | 122,015 | 355,435 | 1,635,001 | 8,175,005 |
| -1 | -5 | -23 | -67 | -115 | -335 | -1,061 | -1,541 | -5,305 | -7,705 | -24,403 | -71,087 | -122,015 | -355,435 | -1,635,001 | -8,175,005 |
