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 8,008,175, 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 | 8,008,175 | |
| -1 | -8,008,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,008,175.
Example:
1 x 8,008,175 = 8,008,175
and
-1 x -8,008,175 = 8,008,175
Notice both answers equal 8,008,175
With that explanation out of the way, let's continue. Next, we take the number 8,008,175 and divide it by 2:
8,008,175 ÷ 2 = 4,004,087.5
If the quotient is a whole number, then 2 and 4,004,087.5 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 | 8,008,175 | |
| -1 | -8,008,175 |
Now, we try dividing 8,008,175 by 3:
8,008,175 ÷ 3 = 2,669,391.6667
If the quotient is a whole number, then 3 and 2,669,391.6667 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 | 8,008,175 | |
| -1 | -8,008,175 |
Let's try dividing by 4:
8,008,175 ÷ 4 = 2,002,043.75
If the quotient is a whole number, then 4 and 2,002,043.75 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 | 8,008,175 | |
| -1 | 8,008,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 67 | 175 | 335 | 469 | 683 | 1,675 | 2,345 | 3,415 | 4,781 | 11,725 | 17,075 | 23,905 | 45,761 | 119,525 | 228,805 | 320,327 | 1,144,025 | 1,601,635 | 8,008,175 |
| -1 | -5 | -7 | -25 | -35 | -67 | -175 | -335 | -469 | -683 | -1,675 | -2,345 | -3,415 | -4,781 | -11,725 | -17,075 | -23,905 | -45,761 | -119,525 | -228,805 | -320,327 | -1,144,025 | -1,601,635 | -8,008,175 |
