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 3,788,855, 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 | 3,788,855 | |
| -1 | -3,788,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,788,855.
Example:
1 x 3,788,855 = 3,788,855
and
-1 x -3,788,855 = 3,788,855
Notice both answers equal 3,788,855
With that explanation out of the way, let's continue. Next, we take the number 3,788,855 and divide it by 2:
3,788,855 ÷ 2 = 1,894,427.5
If the quotient is a whole number, then 2 and 1,894,427.5 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 | 3,788,855 | |
| -1 | -3,788,855 |
Now, we try dividing 3,788,855 by 3:
3,788,855 ÷ 3 = 1,262,951.6667
If the quotient is a whole number, then 3 and 1,262,951.6667 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 | 3,788,855 | |
| -1 | -3,788,855 |
Let's try dividing by 4:
3,788,855 ÷ 4 = 947,213.75
If the quotient is a whole number, then 4 and 947,213.75 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 | 3,788,855 | |
| -1 | 3,788,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 103 | 515 | 721 | 1,051 | 3,605 | 5,255 | 7,357 | 36,785 | 108,253 | 541,265 | 757,771 | 3,788,855 |
| -1 | -5 | -7 | -35 | -103 | -515 | -721 | -1,051 | -3,605 | -5,255 | -7,357 | -36,785 | -108,253 | -541,265 | -757,771 | -3,788,855 |
