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 16,306,031, 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 | 16,306,031 | |
| -1 | -16,306,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,306,031.
Example:
1 x 16,306,031 = 16,306,031
and
-1 x -16,306,031 = 16,306,031
Notice both answers equal 16,306,031
With that explanation out of the way, let's continue. Next, we take the number 16,306,031 and divide it by 2:
16,306,031 ÷ 2 = 8,153,015.5
If the quotient is a whole number, then 2 and 8,153,015.5 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 | 16,306,031 | |
| -1 | -16,306,031 |
Now, we try dividing 16,306,031 by 3:
16,306,031 ÷ 3 = 5,435,343.6667
If the quotient is a whole number, then 3 and 5,435,343.6667 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 | 16,306,031 | |
| -1 | -16,306,031 |
Let's try dividing by 4:
16,306,031 ÷ 4 = 4,076,507.75
If the quotient is a whole number, then 4 and 4,076,507.75 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 | 16,306,031 | |
| -1 | 16,306,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 163 | 217 | 461 | 1,141 | 3,227 | 5,053 | 14,291 | 35,371 | 75,143 | 100,037 | 526,001 | 2,329,433 | 16,306,031 |
| -1 | -7 | -31 | -163 | -217 | -461 | -1,141 | -3,227 | -5,053 | -14,291 | -35,371 | -75,143 | -100,037 | -526,001 | -2,329,433 | -16,306,031 |
