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 16,061,039, 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 | 16,061,039 | |
| -1 | -16,061,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,061,039.
Example:
1 x 16,061,039 = 16,061,039
and
-1 x -16,061,039 = 16,061,039
Notice both answers equal 16,061,039
With that explanation out of the way, let's continue. Next, we take the number 16,061,039 and divide it by 2:
16,061,039 ÷ 2 = 8,030,519.5
If the quotient is a whole number, then 2 and 8,030,519.5 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 | 16,061,039 | |
| -1 | -16,061,039 |
Now, we try dividing 16,061,039 by 3:
16,061,039 ÷ 3 = 5,353,679.6667
If the quotient is a whole number, then 3 and 5,353,679.6667 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 | 16,061,039 | |
| -1 | -16,061,039 |
Let's try dividing by 4:
16,061,039 ÷ 4 = 4,015,259.75
If the quotient is a whole number, then 4 and 4,015,259.75 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 | 16,061,039 | |
| -1 | 16,061,039 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 67 | 239 | 1,003 | 1,139 | 3,953 | 4,063 | 14,101 | 16,013 | 67,201 | 239,717 | 272,221 | 944,767 | 16,061,039 |
| -1 | -17 | -59 | -67 | -239 | -1,003 | -1,139 | -3,953 | -4,063 | -14,101 | -16,013 | -67,201 | -239,717 | -272,221 | -944,767 | -16,061,039 |
