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 4,115,555, 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 | 4,115,555 | |
| -1 | -4,115,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,115,555.
Example:
1 x 4,115,555 = 4,115,555
and
-1 x -4,115,555 = 4,115,555
Notice both answers equal 4,115,555
With that explanation out of the way, let's continue. Next, we take the number 4,115,555 and divide it by 2:
4,115,555 ÷ 2 = 2,057,777.5
If the quotient is a whole number, then 2 and 2,057,777.5 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 | 4,115,555 | |
| -1 | -4,115,555 |
Now, we try dividing 4,115,555 by 3:
4,115,555 ÷ 3 = 1,371,851.6667
If the quotient is a whole number, then 3 and 1,371,851.6667 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 | 4,115,555 | |
| -1 | -4,115,555 |
Let's try dividing by 4:
4,115,555 ÷ 4 = 1,028,888.75
If the quotient is a whole number, then 4 and 1,028,888.75 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 | 4,115,555 | |
| -1 | 4,115,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 83 | 211 | 235 | 415 | 1,055 | 3,901 | 9,917 | 17,513 | 19,505 | 49,585 | 87,565 | 823,111 | 4,115,555 |
| -1 | -5 | -47 | -83 | -211 | -235 | -415 | -1,055 | -3,901 | -9,917 | -17,513 | -19,505 | -49,585 | -87,565 | -823,111 | -4,115,555 |
