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 8,831,615, 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 | 8,831,615 | |
| -1 | -8,831,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,831,615.
Example:
1 x 8,831,615 = 8,831,615
and
-1 x -8,831,615 = 8,831,615
Notice both answers equal 8,831,615
With that explanation out of the way, let's continue. Next, we take the number 8,831,615 and divide it by 2:
8,831,615 ÷ 2 = 4,415,807.5
If the quotient is a whole number, then 2 and 4,415,807.5 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 | 8,831,615 | |
| -1 | -8,831,615 |
Now, we try dividing 8,831,615 by 3:
8,831,615 ÷ 3 = 2,943,871.6667
If the quotient is a whole number, then 3 and 2,943,871.6667 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 | 8,831,615 | |
| -1 | -8,831,615 |
Let's try dividing by 4:
8,831,615 ÷ 4 = 2,207,903.75
If the quotient is a whole number, then 4 and 2,207,903.75 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 | 8,831,615 | |
| -1 | 8,831,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 83 | 415 | 1,079 | 1,637 | 5,395 | 8,185 | 21,281 | 106,405 | 135,871 | 679,355 | 1,766,323 | 8,831,615 |
| -1 | -5 | -13 | -65 | -83 | -415 | -1,079 | -1,637 | -5,395 | -8,185 | -21,281 | -106,405 | -135,871 | -679,355 | -1,766,323 | -8,831,615 |
