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 3,808,175, 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 | 3,808,175 | |
| -1 | -3,808,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,808,175.
Example:
1 x 3,808,175 = 3,808,175
and
-1 x -3,808,175 = 3,808,175
Notice both answers equal 3,808,175
With that explanation out of the way, let's continue. Next, we take the number 3,808,175 and divide it by 2:
3,808,175 ÷ 2 = 1,904,087.5
If the quotient is a whole number, then 2 and 1,904,087.5 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 | 3,808,175 | |
| -1 | -3,808,175 |
Now, we try dividing 3,808,175 by 3:
3,808,175 ÷ 3 = 1,269,391.6667
If the quotient is a whole number, then 3 and 1,269,391.6667 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 | 3,808,175 | |
| -1 | -3,808,175 |
Let's try dividing by 4:
3,808,175 ÷ 4 = 952,043.75
If the quotient is a whole number, then 4 and 952,043.75 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 | 3,808,175 | |
| -1 | 3,808,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 47 | 175 | 235 | 329 | 463 | 1,175 | 1,645 | 2,315 | 3,241 | 8,225 | 11,575 | 16,205 | 21,761 | 81,025 | 108,805 | 152,327 | 544,025 | 761,635 | 3,808,175 |
| -1 | -5 | -7 | -25 | -35 | -47 | -175 | -235 | -329 | -463 | -1,175 | -1,645 | -2,315 | -3,241 | -8,225 | -11,575 | -16,205 | -21,761 | -81,025 | -108,805 | -152,327 | -544,025 | -761,635 | -3,808,175 |
