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 8,483,915, 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 | 8,483,915 | |
| -1 | -8,483,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,483,915.
Example:
1 x 8,483,915 = 8,483,915
and
-1 x -8,483,915 = 8,483,915
Notice both answers equal 8,483,915
With that explanation out of the way, let's continue. Next, we take the number 8,483,915 and divide it by 2:
8,483,915 ÷ 2 = 4,241,957.5
If the quotient is a whole number, then 2 and 4,241,957.5 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 | 8,483,915 | |
| -1 | -8,483,915 |
Now, we try dividing 8,483,915 by 3:
8,483,915 ÷ 3 = 2,827,971.6667
If the quotient is a whole number, then 3 and 2,827,971.6667 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 | 8,483,915 | |
| -1 | -8,483,915 |
Let's try dividing by 4:
8,483,915 ÷ 4 = 2,120,978.75
If the quotient is a whole number, then 4 and 2,120,978.75 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 | 8,483,915 | |
| -1 | 8,483,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 121 | 185 | 379 | 407 | 605 | 1,895 | 2,035 | 4,169 | 4,477 | 14,023 | 20,845 | 22,385 | 45,859 | 70,115 | 154,253 | 229,295 | 771,265 | 1,696,783 | 8,483,915 |
| -1 | -5 | -11 | -37 | -55 | -121 | -185 | -379 | -407 | -605 | -1,895 | -2,035 | -4,169 | -4,477 | -14,023 | -20,845 | -22,385 | -45,859 | -70,115 | -154,253 | -229,295 | -771,265 | -1,696,783 | -8,483,915 |
