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 16,315,159, 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 | 16,315,159 | |
| -1 | -16,315,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,315,159.
Example:
1 x 16,315,159 = 16,315,159
and
-1 x -16,315,159 = 16,315,159
Notice both answers equal 16,315,159
With that explanation out of the way, let's continue. Next, we take the number 16,315,159 and divide it by 2:
16,315,159 ÷ 2 = 8,157,579.5
If the quotient is a whole number, then 2 and 8,157,579.5 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 | 16,315,159 | |
| -1 | -16,315,159 |
Now, we try dividing 16,315,159 by 3:
16,315,159 ÷ 3 = 5,438,386.3333
If the quotient is a whole number, then 3 and 5,438,386.3333 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 | 16,315,159 | |
| -1 | -16,315,159 |
Let's try dividing by 4:
16,315,159 ÷ 4 = 4,078,789.75
If the quotient is a whole number, then 4 and 4,078,789.75 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 | 16,315,159 | |
| -1 | 16,315,159 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 163 | 181 | 553 | 1,141 | 1,267 | 12,877 | 14,299 | 29,503 | 90,139 | 100,093 | 206,521 | 2,330,737 | 16,315,159 |
| -1 | -7 | -79 | -163 | -181 | -553 | -1,141 | -1,267 | -12,877 | -14,299 | -29,503 | -90,139 | -100,093 | -206,521 | -2,330,737 | -16,315,159 |
