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 4,478,815, 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 | 4,478,815 | |
| -1 | -4,478,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,478,815.
Example:
1 x 4,478,815 = 4,478,815
and
-1 x -4,478,815 = 4,478,815
Notice both answers equal 4,478,815
With that explanation out of the way, let's continue. Next, we take the number 4,478,815 and divide it by 2:
4,478,815 ÷ 2 = 2,239,407.5
If the quotient is a whole number, then 2 and 2,239,407.5 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 | 4,478,815 | |
| -1 | -4,478,815 |
Now, we try dividing 4,478,815 by 3:
4,478,815 ÷ 3 = 1,492,938.3333
If the quotient is a whole number, then 3 and 1,492,938.3333 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 | 4,478,815 | |
| -1 | -4,478,815 |
Let's try dividing by 4:
4,478,815 ÷ 4 = 1,119,703.75
If the quotient is a whole number, then 4 and 1,119,703.75 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 | 4,478,815 | |
| -1 | 4,478,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 605 | 673 | 1,331 | 3,365 | 6,655 | 7,403 | 37,015 | 81,433 | 407,165 | 895,763 | 4,478,815 |
| -1 | -5 | -11 | -55 | -121 | -605 | -673 | -1,331 | -3,365 | -6,655 | -7,403 | -37,015 | -81,433 | -407,165 | -895,763 | -4,478,815 |
