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 16,126,319, 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 | 16,126,319 | |
| -1 | -16,126,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,126,319.
Example:
1 x 16,126,319 = 16,126,319
and
-1 x -16,126,319 = 16,126,319
Notice both answers equal 16,126,319
With that explanation out of the way, let's continue. Next, we take the number 16,126,319 and divide it by 2:
16,126,319 ÷ 2 = 8,063,159.5
If the quotient is a whole number, then 2 and 8,063,159.5 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 | 16,126,319 | |
| -1 | -16,126,319 |
Now, we try dividing 16,126,319 by 3:
16,126,319 ÷ 3 = 5,375,439.6667
If the quotient is a whole number, then 3 and 5,375,439.6667 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 | 16,126,319 | |
| -1 | -16,126,319 |
Let's try dividing by 4:
16,126,319 ÷ 4 = 4,031,579.75
If the quotient is a whole number, then 4 and 4,031,579.75 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 | 16,126,319 | |
| -1 | 16,126,319 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 83 | 187 | 913 | 1,039 | 1,411 | 11,429 | 15,521 | 17,663 | 86,237 | 194,293 | 948,607 | 1,466,029 | 16,126,319 |
| -1 | -11 | -17 | -83 | -187 | -913 | -1,039 | -1,411 | -11,429 | -15,521 | -17,663 | -86,237 | -194,293 | -948,607 | -1,466,029 | -16,126,319 |
