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 16,104,115, 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 | 16,104,115 | |
| -1 | -16,104,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,104,115.
Example:
1 x 16,104,115 = 16,104,115
and
-1 x -16,104,115 = 16,104,115
Notice both answers equal 16,104,115
With that explanation out of the way, let's continue. Next, we take the number 16,104,115 and divide it by 2:
16,104,115 ÷ 2 = 8,052,057.5
If the quotient is a whole number, then 2 and 8,052,057.5 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 | 16,104,115 | |
| -1 | -16,104,115 |
Now, we try dividing 16,104,115 by 3:
16,104,115 ÷ 3 = 5,368,038.3333
If the quotient is a whole number, then 3 and 5,368,038.3333 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 | 16,104,115 | |
| -1 | -16,104,115 |
Let's try dividing by 4:
16,104,115 ÷ 4 = 4,026,028.75
If the quotient is a whole number, then 4 and 4,026,028.75 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 | 16,104,115 | |
| -1 | 16,104,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 283 | 599 | 1,415 | 2,995 | 5,377 | 11,381 | 26,885 | 56,905 | 169,517 | 847,585 | 3,220,823 | 16,104,115 |
| -1 | -5 | -19 | -95 | -283 | -599 | -1,415 | -2,995 | -5,377 | -11,381 | -26,885 | -56,905 | -169,517 | -847,585 | -3,220,823 | -16,104,115 |
