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 3,801,395, 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 | 3,801,395 | |
| -1 | -3,801,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,801,395.
Example:
1 x 3,801,395 = 3,801,395
and
-1 x -3,801,395 = 3,801,395
Notice both answers equal 3,801,395
With that explanation out of the way, let's continue. Next, we take the number 3,801,395 and divide it by 2:
3,801,395 ÷ 2 = 1,900,697.5
If the quotient is a whole number, then 2 and 1,900,697.5 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 | 3,801,395 | |
| -1 | -3,801,395 |
Now, we try dividing 3,801,395 by 3:
3,801,395 ÷ 3 = 1,267,131.6667
If the quotient is a whole number, then 3 and 1,267,131.6667 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 | 3,801,395 | |
| -1 | -3,801,395 |
Let's try dividing by 4:
3,801,395 ÷ 4 = 950,348.75
If the quotient is a whole number, then 4 and 950,348.75 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 | 3,801,395 | |
| -1 | 3,801,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 233 | 251 | 1,165 | 1,255 | 3,029 | 3,263 | 15,145 | 16,315 | 58,483 | 292,415 | 760,279 | 3,801,395 |
| -1 | -5 | -13 | -65 | -233 | -251 | -1,165 | -1,255 | -3,029 | -3,263 | -15,145 | -16,315 | -58,483 | -292,415 | -760,279 | -3,801,395 |
