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 3,855,515, 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 | 3,855,515 | |
| -1 | -3,855,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,855,515.
Example:
1 x 3,855,515 = 3,855,515
and
-1 x -3,855,515 = 3,855,515
Notice both answers equal 3,855,515
With that explanation out of the way, let's continue. Next, we take the number 3,855,515 and divide it by 2:
3,855,515 ÷ 2 = 1,927,757.5
If the quotient is a whole number, then 2 and 1,927,757.5 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 | 3,855,515 | |
| -1 | -3,855,515 |
Now, we try dividing 3,855,515 by 3:
3,855,515 ÷ 3 = 1,285,171.6667
If the quotient is a whole number, then 3 and 1,285,171.6667 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 | 3,855,515 | |
| -1 | -3,855,515 |
Let's try dividing by 4:
3,855,515 ÷ 4 = 963,878.75
If the quotient is a whole number, then 4 and 963,878.75 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 | 3,855,515 | |
| -1 | 3,855,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 67 | 85 | 335 | 677 | 1,139 | 3,385 | 5,695 | 11,509 | 45,359 | 57,545 | 226,795 | 771,103 | 3,855,515 |
| -1 | -5 | -17 | -67 | -85 | -335 | -677 | -1,139 | -3,385 | -5,695 | -11,509 | -45,359 | -57,545 | -226,795 | -771,103 | -3,855,515 |
