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 16,376,705, 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 | 16,376,705 | |
| -1 | -16,376,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,376,705.
Example:
1 x 16,376,705 = 16,376,705
and
-1 x -16,376,705 = 16,376,705
Notice both answers equal 16,376,705
With that explanation out of the way, let's continue. Next, we take the number 16,376,705 and divide it by 2:
16,376,705 ÷ 2 = 8,188,352.5
If the quotient is a whole number, then 2 and 8,188,352.5 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 | 16,376,705 | |
| -1 | -16,376,705 |
Now, we try dividing 16,376,705 by 3:
16,376,705 ÷ 3 = 5,458,901.6667
If the quotient is a whole number, then 3 and 5,458,901.6667 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 | 16,376,705 | |
| -1 | -16,376,705 |
Let's try dividing by 4:
16,376,705 ÷ 4 = 4,094,176.25
If the quotient is a whole number, then 4 and 4,094,176.25 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 | 16,376,705 | |
| -1 | 16,376,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 109 | 151 | 199 | 545 | 755 | 995 | 16,459 | 21,691 | 30,049 | 82,295 | 108,455 | 150,245 | 3,275,341 | 16,376,705 |
| -1 | -5 | -109 | -151 | -199 | -545 | -755 | -995 | -16,459 | -21,691 | -30,049 | -82,295 | -108,455 | -150,245 | -3,275,341 | -16,376,705 |
