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 3,996,175, 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 | 3,996,175 | |
| -1 | -3,996,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,996,175.
Example:
1 x 3,996,175 = 3,996,175
and
-1 x -3,996,175 = 3,996,175
Notice both answers equal 3,996,175
With that explanation out of the way, let's continue. Next, we take the number 3,996,175 and divide it by 2:
3,996,175 ÷ 2 = 1,998,087.5
If the quotient is a whole number, then 2 and 1,998,087.5 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 | 3,996,175 | |
| -1 | -3,996,175 |
Now, we try dividing 3,996,175 by 3:
3,996,175 ÷ 3 = 1,332,058.3333
If the quotient is a whole number, then 3 and 1,332,058.3333 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 | 3,996,175 | |
| -1 | -3,996,175 |
Let's try dividing by 4:
3,996,175 ÷ 4 = 999,043.75
If the quotient is a whole number, then 4 and 999,043.75 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 | 3,996,175 | |
| -1 | 3,996,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 47 | 95 | 179 | 235 | 475 | 893 | 895 | 1,175 | 3,401 | 4,465 | 4,475 | 8,413 | 17,005 | 22,325 | 42,065 | 85,025 | 159,847 | 210,325 | 799,235 | 3,996,175 |
| -1 | -5 | -19 | -25 | -47 | -95 | -179 | -235 | -475 | -893 | -895 | -1,175 | -3,401 | -4,465 | -4,475 | -8,413 | -17,005 | -22,325 | -42,065 | -85,025 | -159,847 | -210,325 | -799,235 | -3,996,175 |
